Acriflavine HCl is a compound predominantly used in cellular biology for fluorescence staining. It intercalates between the base pairs of DNA and RNA. Among the acridine dyes, acriflavine has the highest affinity for DNA. Acriflavine stains eukaryotic cells exceptionally well in humic substance environments. It provides a robust experimental consistency and reduces the effect of minor experimental errors. The binding of acriflavine to DNA can be observed from a characteristic red shift in an absorption spectrum. While having a high affinity for DNA, acriflavine is limited to euchromatin for both DNA and RNA.

Acriflavine has also been found to inhibit heterodimeric transcription factors, specifically called hypoxia-inducible factors (HIFs). Studying the hyperactivity of HIFs has become a popular in oncology research, where chemicals like acriflavine are used to disrupt HIF activity of malignant cells. HIFs are activated in hypoxic conditions and promote angiogenesis to alleviate stress. They are normally regulated through proline and asparagine hydroxylation. Acriflavine halts HIF activity, specifically by binding to a subdomain of HIF-1α and HIF-2α.

Actinomycin D is an antineoplastic antibiotic from Streptomyces species that inhibits cell proliferation by acting as a cytotoxic inducer of apoptosis against tumor cells, binding to DNA and inhibiting RNA polymerase activity. Actinomycin is also used in plant tissue culture to inhibit plant growth through tissue deformation where it also acts as an RNA-synthesis inhibitor. Along with its fluorescent derivative, 7aminoactinomycinD (7-AAD), Actinomycin is used to stain GC-rich regions of DNA for microscopy and flow cytometry applications.

Acycloguanosine is a guanosine analogue that is synthetically formed. It is markedly effective against the herpesvirus family, especially HSV (herpes simplex viruses) types one and two. Lab results have shown susceptibility to acycloguanosine which varies with the analogue’s concentration, respective to each virus.

Acycloguanosine functions as a HSV DNA polymerase inhibitor by integrating into the viral DNA, terminating polymerization. Integration occurs after being catalyzed by viral thymidine kinase into acyclovir triphosphate (Acyclo-GTP). Acycloguanosine is ineffective against non-viral genetic material, due to the lack of an appropriate thymidine kinase.

ADA is a zwitterionic buffering agent used in biochemistry and molecular biology that was first selected and described by Good et al. It is an acetamido buffer that is useful for a pH range of 6.0 – 7.2. ADA forms a complex with most common metals and stability constants should be taken into account when using this buffer. It has been used as a complexing agent to effectively help remove contaminant metals from soil. ADA absorbs UV light between 0.1 and 260 nm. Solubility of ADA increases if the free acid is converted to the sodium salt with NaOH.

Adenine 9-beta-D-arabinofuranoside (ara-A) is a synthetically produced purine nucleoside that is used in cell signaling research. It has commonly been used in anti-viral research with hepadnaviridae and herpes simplex viruses. The nucleoside ara-A interferes with viral DNA synthesis, but only in its active phosphorylated form. Active ara-ATP inhibits synthesis by incorporating into viral DNA and preventing phosphodiester bridge formation.

The compound ara-A is a precursor of adenine 9-beta-D-arabinofuranoside 5’monophosphate (ara-AMP). In vivo rat experiments of ara-AMP have shown a higher solubility and affinity for some proteins, both of which facilitate ara-AMP movement. Isolated human hepatocytes have also been shown to specifically endocytose the albumin/ara-AMP conjugate.

Adenosine is an endogenous nucleoside (comprising a molecule of adenine attached to a ribose sugar molecule) and neurotransmitter that can act as the preferred agonist at adenosine A receptor subtypes. The function of adenosine is primarily for cytoprotection and for preventing tissue damage in response to stress or injury.

Adenosine-5'-monophosphate (AMP) plays an important role in cellular metabolic processes as it is a precursor to adenosine-5'-triphosphate (ATP).

The phosphate in AMP can be correlated with ATP and ADP. AMP contains only one phosphate group attached at the 5’ position, whereas ATP consists of three phosphate groups attached in series to the 5’carbon location, and ADP contains two phosphate groups attached to the 5’ position. AMP can also have an activating effect on a class of protein kinases known as AMP-activated protein kinases, or AMPKs.

Adenosine-5'-triphosphate (ATP) is an important molecule in vivo for energy storage and metabolism and is often called the "molecular unit of currency" of intracellular energy transfer. ATP is a coenzyme in multiple reactions as well as a substrate for multiple kinases where it helps to propagate a signal either inside or outside of the cell.

The three phosphates in ATP can be correlated with ADP and AMP. ATP consists of three phosphate groups attached in series to the 5’carbon location, whereas ADP contains two phosphate groups attached to the 5’ position, and AMP contains only one phosphate group attached at the 5’ position.

Adonitol, also known as ribitol, is the reduced alcohol form of ribose. Adonitol is found in plants of the genus Adonis, from which the molecule takes its name. It is a component of teichoic acids found in the cell walls of Gram positive bacteria. Adonitol is also a moiety present in riboflavin (vitamin B2). Adonitol is commonly used in media for cryopreservation and lyophilization of cells. It is metabolized by some microbes, but not others so an adonitol fermentation test can be used to help identify an unknown microbial organism.

AEBSF is an irreversible serine protease inhibitor. AEBSF has been shown to inhibit trypsin, chymotrypsin, plasmin, kallikrein and thrombin. It inhibits the active site of the enzyme through acylation. As an alternative to PMSF and DFP, AEBSF offers lower toxicity, improved solubility in water and improved stability in aqueous solutions. AEBSF has been used in cell culture in concentrations of up to 0.25 mM. Aqueous solutions are stable between pH 5-6; limited stability above pH 7.5.

Agarose LE (Low Electroendosmosis) is Molecular Biology Grade and is specifically designed for the superior separation of nucleic acids, with maximally crisp band resolution, and is also ideal for cloning and cloning related experiments.

GoldBio Agarose LE is refined in an advanced process that excludes the use of organic solvents. The result is a cleaner end-product with significantly reduced environmental impact. The agarose can be used for analyses of nucleic acids from 50 bp to 25 kbp, protein electrophoresis and various blotting protocols.

The low EEO of the agarose promotes increased electrophoretic mobility, yielding improved resolution and shorter run times. This also allows macromolecules and larger particles (subcellular fragments, viruses, etc.) to migrate more freely through the gel matrix. The consistently low EEO reduces band distortion (caused by counterflow) that can result from the presence of excessive sulfate-rich negative ions.

Agarose is a natural product that forms an inert matrix used in electrophoresis, chromatography and other molecular biology and biochemistry techniques. Likewise, it is neutral and easily derivatizable, so it is easy to bind to its structure proteins like enzymes, antigens or antibodies. Toxicity absence makes working with agarose very convenient.

GoldBio’s AGL-1 Agrobacterium chemically competent cells allow you to obtain high transformation efficiency in applications such as gDNA or cDNA library construction. Our AGL-1 strain harbors the C58 chromosomal backbone with an insertion mutation in its recA recombination gene. This mutation stabilizes recombinant plasmids. AGL-1 also has rifampicin and carbenicillin resistance genes in the genome useful for selection. A functional T-DNA binary system can be built using our AGL-1 strains as the T-DNA region has been deleted from the Ti plasmid pTiBO542 and instead it has a binary vector containing the missing T-region. The binary system makes possible to transfer genetic material into a host plant S genome. Therefore, our system is often used for Agrobacterium-mediated transformation in mono and dicotyledonous species such as Arabidopsis thaliana, maize, and other plants.

pSuperAgro™ v4 was designed to include AcdS and GabT activity, driven by a single lac promotor, which both suppresses ethylene evolution and degrades gamma-aminobutyric acid (GABA) during co-cultivation. The combined suppression of ethylene and reduction of GABA significantly increases T-DNA transfer and increases transient and stable transformation frequencies in both tomato and grass plants.
