Bacitracin methylenedisalicylate

Steptavidin, a bacterial protein isolated from Streptomyces avidinii, is similar to egg-white avidin in its ability to bind biotin, and has been used as a replacement for egg-white avidin because of its more favorable chemical properties. Conjugates

Bacitracin is a polypeptide antibiotic produced by strains of Bacillus subtilis and Bacillus licheniformis . Bacitracin A is a commercially produced, major microbiologically active component of bacitracin.

Bacteriorhodopsin (BR) is a covalent complex comprising bacterioopsin protein and retinal cofactor in the equimolar ratio. It corresponds to the molecular weight of 27kDa.

Features and Benefits Biotin-dPEG &#174: 7 -amine is a single molecular weight dPEG &#174: product containing a terminal primary amine that permits biotin labeling with precise spacing to molecules containing a free carboxylic acid or aldehyde

Biotin-PEG7-amine is PEG derivative containing a biotin group and a terminal primary amine group. The amine group can be coupled to carboxyl groups or 5'phosphate groups to form stable amide bonds. The hydrophilic PEG spacer increases solubility in
