Bioluminescence is the production and emission of light by a living organism. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms and terrestrial invertebrates. Luciferin, the firefly substrate of luciferase, is a common reagent used throughout the biotechnology field. The injection of luciferin allows for the real-time, noninvasive monitoring of disease progression and/or drug efficacy in these model systems through Bioluminescence Imaging (BLI). Coelenterazine is a luminophore is the substrate for many luciferase enzymes, including Renilla reniformis, gaussia, and aequorins. It is commonly used to monitor reporter genes in BRET (Bioluminescence Resonance Energy Transfer), ELISA and HTS methods. Gold Biotechnology’s luciferin and coelenterazine are Proven and Published™ to ensure a quality reagent with optimal potential. ORDER NOW!
IPTG is an analog of galactose that is nonmetabolizable and inactivates the lac repressor to induce synthesis of β-galactosidase in E. coli. The expression of cloned genes under the control of the lac operon is induced by IPTG. IPTG is often used in the induction of recombinant proteins, is a substrate for thigalactoside transacetylase and has been reported to induce penicillinase in bacteria. IPTG is commonly used in cloning procedures that require induction of β-galactosidase and is most often used with X-Gal for blue/white bacterial colony screening. GoldBio’s is most cost effective IPTG on the market, without sacrificing quality or purity. Gold Biotechnology IPTG is Proven and Published™ and is a better way to generate the experimental results you need while focusing your budget on the things that really matter. ORDER NOW!
TCEP (Tris (2-Carboxyethyl) phosphine Hydrochloride) is an odorless reducing agent suitable for protein applications and in the preparation for electrophoresis. TCEP is water soluble, is stable in a variety of solutions and is particularly useful in the labeling of cysteine residues with maleimides, preventing the cysteines from forming disulfide bonds. As a reducing agent, TCEP has many other desirable features, including: – TCEP-HCl is stable in air. – TCEP-HCl is odorless so reactions can be carried out on the bench without the need for a fume hood. – TCEP-HCl is efficient and can be used to reduce disulfide bonds at low concentrations. – TCEP-HCl may be used as a substitute for DTT at a final concentration of 50mM.
