Description

2-keto-D-gluconic acid is found in the carrageenan polysaccharide of Irish moss and can be used as a stabilizer in the storage of biological materials. 2-keto-D-gluconic acid exhibits antimicrobial properties against species of Pseudomonas that cause plant disease. Genes for metabolism of 2-keto-d-gluconic acid are controlled by the UxuR regulon in E. coli. 2-keto-D-gluconic acid is converted to D-mannonate by the enzyme fructuronate reductase (EC 1.1.1.57). 2-keto-D-gluconic acid hemicalcium salt can be used to make D-erythorbic acid using an α-amylase enzyme. It can also be used to prepare D-ribulose and D-arabinose by heating in pyridine with a nickel acetate catalyst.

Description

2-Ketoglutaric acid is a ketone derivative of glutaric acid and its anion is key intermediate in the Krebs cycle, after isocitrate and before succinyl CoA. It is an important nitrogen transporter and is transaminate along with glutamine to form glutamate. It can be used to differentiate microorganisms based on metabolic properties. It also possesses metabolic properties, decreasing the level of hydrogen peroxide in cell culture.

Description

FGF10/KGF2 is a member of the Fibroblast Growth Factor family of proteins. KGF2 cDNA encodes a 208 amino acid residue protein with a hydrophobic amino-terminal signal peptide. Human KGF2 shares 92% and 95% amino acid sequence identity with mouse and rat KGF2, respectively. In the FGF family, KGF2 is most closely related to FGF7 (KGF1), FGF3 and FGF22 (see additional information). The expression of KGF2 transcript has been shown to be most abundant in the embryo and adult lung. Recombinant KGF2 has been shown to be mitogenic for epithelial and epidermal cells but not fibroblasts. KGF2 may play unique roles in brain and lung development, wound healing and limb bud formation.

I-925-1000 1000 Assays $ 553.00

Description

GoldBio’s Illumination™ Renilla Luciferase Enhanced Assay Kit is specifically designed for the measurement of Renilla luciferase in transfected cell reporter gene assays. This kit is enhanced with a water soluble coelenterazine that is easier to use and store than other conventional coelenterazine products.

Renilla luciferase is a commonly used bioluminescent reporter gene that is used to study gene regulation and function both in vivo as well as in vitro. Renilla luciferase is a monomeric 36 kDa protein isolated from the sea pansy, Renilla reniformis, which catalyzes coelenterazine with oxygen to produce a blue light (480 nm). There is no need for any post-translational modifications and the protein may be used as a gene reporter immediately after translation. Our Enhanced Assay Kit includes a special buffer which is designed to yield reliable, linear measurements of Renilla luciferase activity with maximum sensitivity and minimal autoluminescence. This kit is a flash-type luminescent assay, and requires measurement immediately after adding the substrate to the sample.

One Assay can be performed in a single tube or an individual well on a 96 well plate. The kits include enough Passive Lysis Buffer to perform the stated number of assays in plate sizes ranging from 96-well to 24-well. If needed, additional 5X Passive Lysis Buffer (GoldBio Catalog # L-745) can be purchased separately.

Description

GoldBio’s Illumination™ Dura-Luc Lyophilized Firefly HTS Assay Kit contains a proprietary formulation that modifies and stabilizes the enzymatic reaction to produce a long lasting bioluminescent signal by preventing the formation of adenyl-oxyluciferin at the enzyme surface. The Dura-Luc system is a highly sensitive and homogenous luciferase reporter assay that has a signal half-life of three hours for the best quantification of expression in mammalian cell lines, allowing for batch processing and plate to plate comparisons in high-throughput screening experiments.

Firefly Luciferase Assays are one of the leading reporter assays in the world in the measurement of gene function and gene regulation as well as being widely used in pharmaceutical screening. The luciferase assays are sensitive and convenient due to the absence of endogenous luciferase activity in most cell types and tissue. Firefly luciferase is a monomeric 62 kDa protein typically isolated from the firefly, Photinus pyralis, which catalyzes the ATP-dependent D-luciferin in the presence of oxygen and Mg2+ to oxyluciferin producing a yellow to greenish light (~560 nm).

The Dura-Luc Lyophilized Firefly Kit contains an assay buffer that is provided in a lyophilized form for economical shipping and more convenient storage. A reconstitution buffer is also provided with this kit.

Description

GoldBio’s Illumination™ Firefly & Renilla Luciferase Enhanced Assay Kit is a combined luciferase assay allowing the sequential measurement of Firefly and Renilla luciferase activity in the same sample while still retaining the highest degree of sensitivity, reliability and linearity that you want in your assay. Firefly activity is measured first, then the Renilla Luciferase Assay Buffer is added to the sample to simultaneously extinguish all firefly luciferase activity to the level of untransformed cells and begins the Renilla luciferase activity. This great luciferase combo allows the sequential measurement of both luciferase assays in the same sample without additional hassle.

This kit is a flash-type luminescent assay, and requires measurement immediately after adding the detection reagents to the sample. The Enhanced Assay Kit includes our water soluble coelenterazine that is easier to use and store than other conventional coelenterazine products.

One Assay can be performed in a single tube or an individual well on a 96 well plate. The kits include enough Passive Lysis Buffer to perform the stated number of assays in plate sizes ranging from 96-well to 24-well.

Description

FOR RESEARCH USE ONLY. NOT FOR USE ON HUMANS.

Kinetin is a plant hormone that promotes cell division. It is part of a group of hormones called cytokinins.

The plant hormones cytokinins (CKs) comprise a class of growth regulators involved in the stress response, senescence, photosynthesis, nutrient assimilation and mobilization, as well as modulation of a plant tissue’s ability to act as a sink or source of metabolites.

CKs are recognized by a subset of sensor histidine kinases (HKs) and the signal is transmitted to the nucleus via a multistep phosphorelay (MSP), thus activating the expression of target genes.

Catalog ID Size Pricing
1420-01-10 10 μg $ 149.00

Description

KIT Ligand (KITLG), also called Stem Cell Factor (SCF) which binds to the c-Kit receptor is produced by fibroblasts and endothelial cells. The soluble and transmembrane forms of the protein are formed by alternative splicing of the same RNA transcript and the presence of both soluble and transmembrane SCF is required for normal hematopoietic function. SCF plays an important role in hematopoiesis, spermatogenesis and melanogenesis and it promotes mast cell adhesion, migration, proliferation, and survival. Soluble canine SCF shares 76-93% amino acid sequence identity with many other species, including human, mouse, rat and equine. Cells known to express SCF include endothelial cells, fibroblasts and keratinocytes.

Description

C-kit ligand, the recently identified ligand for the kit tyrosine kinase receptor, is mapped to the mouse S1 locus. This pleiotropic cytokine, alternately known as stem cell factor (SCF), mast cell growth factor (MGF) and steel-factor (SLF), plays essential roles in gametogenesis, melanogenesis and early stages of hematopoiesis. In vitro and in vivo KITLG can stimulate the proliferation of mature, as well as the proliferation and maturation of immature mast cells. KITLG acts in a synergistic manner on purified primitive human and mouse hematopoietic precursors, with various growth factors (such as IL1, IL3, IL6, IL7 and Epo,) to induce myeloid, erythroid and lymphoid lineage colony formation. The finding that KITLG is also expressed in the nervous system suggests a possible role for KITLG in the development of the nervous system.
