The Gentamicin EZ Pak™ is the fastest and easiest way to make a set amount of sterile gentamicin solution. The kit includes pre-weighed gentamicin powder, a sterile filter and a sterile container for the filtered solution. No need to calculate, simply add the stated amount of deionized H₂O, filter, and pour into the labeled bottle for easy usage. The EZ Pak™ includes high quality GoldBio gentamicin and the sterile solution is ready for tissue culture, bacterial media, or any number of uses.

Gentamicin is an aminoglycoside, broad-spectrum antibiotic that effectively inhibits Gram-negative and Gram-positive cell growth. Gentamicin's mode of action is to bind to the 30S ribosomal subunit and interfere with protein synthesis.

It is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against gram-positive and gram-negative microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options for infected patients.

Germacrone is an essential oil extracted from Rhizoma curcuma and has been used as an anti-cancer and anti-viral agent. It has been shown to eliminate hepatic and breast cancer cell lines by inhibiting cyclin dependent kinase 2 (CDK2) activity. It has also been shown to upregulate apoptotic protein expression.

Inhibition of viral replication by germacrone occurs early in the virus cycle. When used against influenza, germacrone inhibited in vivo and in vitro viral replication by inhibiting viral RNA and protein synthesis. This prevents viral replication after splicing DNA by removing the needed materials for proliferation.

Quick-Dissolve™ Gibberellic Acid is a special formulation developed at GoldBio that dissolves more easily in water than standard gibberellic Acid. In our lab, KOH is not required to drive the Quick-Dissolve™ Gibberellic Acid into solution.

Gibberellic Acid 4 + 7 is a growth regulator that acts by stimulating rapid stem and root growth, induces mitotic division in the leaves of some plants and increase seed germination rate.

Glucose oxidase comes from Aspergillus niger and has many applications. Glucose oxidase can be used in the determination of glucose in colorimetric assays in conjunction with peroxidase, in the determination of glucose biosensors or for use as an enzyme label.

Glutathione has been covalently linked for use in affinity purification of glutathione-S-transferase (GST) and GST fusion proteins.

Glutathione, Oxidized (GSSG) is the oxidized version of the naturally occurring and very important detoxification agent glutathione (GSH). When used in vivo, GSSG will not remain oxidized, but rather be reduced back to GSH. A ratio of GSH to GSSG can be used to determine the level of oxidative stress that has occurred in cells. When a cell has higher levels of GSSG, then it can be implied that more oxidative stress has occurred within the cell.

Glycine has many applications. As an amino acid, it is found as a biological molecule in the central nervous system and has inhibitory effect, especially in the spinal cord, brainstem and retina; and is also a precursor to proteins. In eukaryotes it is an important precursor to porphyrins, and provides the C2N subunit of all purines. For the purposes of testing glycine is a significant component of some solutions used in SDS-PAGE protein analysis as a buffering agent and for removing labelling antibodies from Western Blot membranes. Glycine methyl ester is a reagent used in chemical synthesis, it can synthesize selenohydantoins when used in addition to isoselenocyanate.

Because of its charge properties and small size, glycine is commonly used as a counter-ion in SDS-PAGE applications to balance running buffer charge and electric field strength.

Glycochenodeoxycholic acid (GCDC) is a bile salt that is used as an anionic detergent to solubilize lipids. In other applications GCDC can be used to induce hepatocyte apoptosis and inhibit calcium phosphate precipitation in vitro. GCDC is also used in applications analyzing the damage done to DNA by other bile acids.

Glycocholic acid, sodium salt hydrate is an ionic biologic detergent formed through the conjugation of cholic acid with glycine. It is used to measure total bile acids through fluorometric and enzymatic assays. Additionally, it is used to study its effect on testosterone micelle formation and solubilization.

Biomolecules can be immobilized by binding them to a support under conditions that will then determine the characteristics of the complex. Immobilization is a technique that binds a ligand (enzyme, antibody, affinity proteins like Protein A or Protein G) to a support, giving high stability and making it easier to reuse the immobilized molecule.

Glyoxal beads allow a covalent binding of agarose to lysine amino groups (similar orientation to CNBr). Glyoxal agarose beads are ready to use and require no activation. The resin has a high amount of aldehydes groups (40-60 µmoles Glyoxal / ml gel) providing a very good option to conjugate affinity ligands improving the stability of the ligand.

The choice of Glyoxal or Aminoethyl will depend on the biomolecule to be immobilized, the accessibility of the reactive groups, and the direction/ orientation required for the binding to the support.

Glyoxal beads allow a covalent binding of agarose to lysine amino groups (similar orientation to CNBr). Glyoxal agarose beads are ready to use and require no activation. The resin has a high amount of aldehydes groups (15-25 µmoles Glyoxal / ml gel) providing a very good option to conjugate affinity ligands improving the stability of the ligand.

Glyoxal HTC 6% HIGH Density Agarose beads allow covalent binding of agarose to lysine amino groups (similar orientation to CNBr).

This product is adequate to work in large scale process (High Pressure). The resin has a high amount of aldehyde groups (40-60 µmoles Glyoxal / ml gel) providing multiple binding points and high immobilized ligand stability. The resin has been manufactured using 6% HTC agarose beads, and the pore size is adequate to work with enzymes, proteins & small ligands. The stability at high flow is adequate for large scale process.

Glia maturation factor beta is an actin-binding protein that shows sequence similarity to the ADF/ cofilin family. It is expressed in the cytosol and on the cell surface of astrocytes and interacts with target receptors in a juxtacrine manner. GMFB is involved in the differentiation of glial cells and neurons. It stimulates axon regeneration and proliferation of astroblasts, and inhibits proliferation of tumors. It also reversibly inhibits proliferation of neuronal and non-neuronal neoplastic cells by arresting the cell cycle in the G0/G1 phase. It is suggested that GMFB acts an intracellular regulator of signal pathways.
