Ciliary neurotrophic factor (CNTF) is a polypeptide hormone whose actions appear to be restricted to the nervous system where it promotes neurotransmitter synthesis and neurite outgrowth in certain neuronal populations. It was initially identified as a trophic factor for embryonic chick ciliary parasympathetic neurons in culture. The protein is also a potent survival factor for neurons and oligodendrocytes and may be relevant in reducing tissue destruction during inflammatory attacks. In addition, CNTF is useful for treatment of motor neuron disease and it could reduce food intake without causing hunger or stress. CNTF is structurally related to IL6, IL11, LIF, and OSM. All of these four helix bundle cytokines share gp130 as a signal-transducing subunit in their receptor complexes.

Available in bulk or in prepacked columns, cobalt has a binding capacity of >25 mg/ml with approximately 60 kDa protein. Cobalt binds fewer host protein contaminants, resulting in lower background than nickel resins and no metal contamination in eluted histidine-tagged protein sample. In addition, it allows for purification of proteins under native or denaturing conditions. Cobalt Agarose works very well with Ni/Cu/Co Resin Wash Buffer and Histidine Protein Elution Buffer.

Cobalt HTC 6% Agarose Beads are suitable for downstream purification using IMAC. These resins combine the advantages of Cobalt purification with the high flow rates of the HTC resin (70% higher than commercial standards).

Coelenterazine is a luminophore found in aquatic organisms and is the substrate for many luciferase enzymes, including Renilla reniformis, Gaussia and aequorins. It is commonly used for bioluminescent calcium detection and the monitoring of reporter genes in BRET (Bioluminescence Resonance Energy Transfer), ELISA and HTS methods as well as chemiluminescent detection of superoxide anions and peroxynitrite in cells or tissues.

Coelenterazine 400a is a derivative of coelenterazine and is a good substrate for Renilla reniformis luciferase (RLuc), but does not oxidize well with Gaussia (GLuc). It is the preferred substrate for BRET (Bioluminescence Resonance Energy Transfer) since its emission maximum of 400nm has minimal interference with the GFP emission.

Colchicine is an alkaloid isolated from Colchicum autumnale and other Colchica species. It is an antimitotic agent useful against various cancer cell lines. Colchicine disrupts microtubules and can be used to induce tetraploidy in plant cells. It is an activator of the JNK/SAPK signaling pathway and used to select for cells containing MDCK (NBL-2) resistance. Colchicine’s antimitotic properties are more effective against cancer cells due to their increased mitotic rate compared to that of healthy cells. Colchicine is useful in cell division studies.

Colistin is a polymyxin antibiotic effective against gram-negative bacteria. It has been used to permeabilize bacterial cell membranes and to study mannose-resistant haemagglutination. It has also been implicated in researching effective treatment for P. aeruginosa infections.

Colistin functions by targeting cell membranes and altering their permeability. Colistin sodium methanesulfonate (CMS) is considered an inactive prodrug, which means it is inactive until converted into colistin by cellular enzymes. GoldBio also offers Colistin sulfate (colistin), the end product of CMS, which does not require molecular conversion for antimicrobial properties.

Colistin is a cyclic polypeptide antibiotic of the polymyxin family. It targets the cell membrane of bacteria, which ultimately leads to an altered cell permeability and cell death. It primarily targets gram-negative bacteria. Colistin has been used to study mannose-resistant haemagglutination, antibiotic resistance, and nephrotoxicity.

Colistin sulfate (colistin) is the end product of Colistin Sodium Methanesulfonate (CMS) and does not require molecular conversion for antimicrobial properties.

Coomassie Brilliant Blue G-250 (CBBG) is a member of the Coomassie family and is used as a common analytical dye in SDS-PAGE and BN-PAGE. CBBG can also be used with the Bradford Method to determine protein concentration.

Coomassie Brilliant Blue R-250 (CBBR) is a member of the Coomassie family and is used extensively as an analytical dye in SDS-PAGE.

Cresol red is a color marker and pH indicator for various laboratory procedures. As a color marker in agarose and polyacrylamide electrophoresis at 1% it runs at 125 base pair size, and as a titrant indicator Cresol Red is yellow below pH 7.2 and purple at pH 8.8 and above. Cresol Red can be used with Taq polymerase because it does not inhibit reactions unlike other dyes and has also been used as a pH sensitive optical fiber sensor.
