Boric Acid

Catalog ID Size Pricing
B-030-500 500 g $ 16.00
B-030-1 1 kg $ 27.00
B-030-5 5 kg $ 117.00

Description

Boric acid is commonly used for the preparation of buffers such as Tris-Borate-EDTA (TBE). Borate buffers have been used in capillary and gel electrophoresis for separating proteins and nucleic acids. The useful buffering range of boric acid is pH 8.2-10.1. In a basic solution, the salt of boric acid forms complex equilibria, with the tetraborate ion (B4O72-) being the most predominant species present. Boric acid is used in catalytic amounts to promote amidation between carboxylic acids and amines. It is capable of forming a complex with various carbohydrates, as well as with pyridine nucleotides, such as NAD+.

Description

ProGlow™ Western Blot Protein Ladders are designed for Western blots. ProGlow™ ladders can be used to monitor electrophoresis progress and to visualize protein standard bands directly on X-ray film or digital analytical equipment. ProGlow™ ladders consist of eight recombinant proteins in the range of 12-90 kDa. The 70 kDa protein is a prestained marker used for monitor of the electrophoresis process and evaluation of Western transfer efficiency. The other seven markers can bind to human, mouse, rat, goat, sheep and rabbit IgG with their IgG binding site, allowing direct visualization of markers on the X-ray film after ECL development.

Description

CAPS is a zwitterionic buffering agent used in biochemistry and molecular biology. It is a cyclohexylamine buffer that is useful for a pH range of 9.7 – 11.1 and commonly used to study enzymatic processes above physiological pH. CAPS is an excellent buffer for the transfer of high molecular weight proteins to nitrocellulose membranes after SDS-PAGE. It is also used in protein sequencing. CAPS displays only weak or negligible complexation capabilities for some metals making it a suitable non-coordinating buffer for use in solutions containing metal ions. CAPS is suitable for use with the bicinchoninic acid (BCA) assay.
