Serine (abbreviated as Ser or S)[3] encoded by the codons UCU, UCC, UCA, UCG, AGU and AGC is an ?-amino acid that is used in the biosynthesis of proteins. It contains an alpha-amino group (which is in the protonated ?NH+ 3 form under biological conditions), a carboxyl group (which is in the deprotonated -COO? form...

(±)-Flurbiprofen is a non-selective COX inhibitor (IC50s = 0.04 and 0.51 µM for COX-1 and COX-2, respectively). In vivo, (±)-flurbiprofen (0.3-4.8 mg/kg, p.o.) reduces carrageenan-induced hind paw edema and yeast-induced fever in rats. (±)-Flurbiprofen reduces plasma fibrinogen levels and arthritic score in a rat...

Zymolyase, produced by a submerged culture of Arthrobacter luteus (1), is an enzyme preparation which effectively lyses cell walls of viable yeast cells. An essential enzyme responsible for lysis of viable yeast cells in this preparation is b-1, 3-glucan laminaripentaohydrolase. It hydrolyzes linear glucose...

Blue substrate used in the detection of b-galactosidase in bacteria or phage as a selection agent for cloning experiments utilizing the lacZ vector. Colonies expressing b-galactosidase will appear blue in the presence of XGAL. Others will appear white. Gene Cloning: In gene cloning, X-gal is used as a visual...

TAPS is a biological buffer (zwitterionic) designed by Good, et al., and typically referred to as Good's buffer useful in cell culture media formulations. Selection of biological buffer systems should include the following criteria: exclusion by biological membranes, low absorption between 240 and 700nm, chemically...

The Gelite(TM) 1 kb DNA Ladder is designed for sizing and estimating the mass of double-stranded DNA and PCR products within the 250 to 10,000 bp range on agarose or polyacrylamide gels. This ladder consists of 13 different DNA fragments that have been purified through chromatography. The 1,000 and 3,000 bp bands...

CF(R) dye labeled dextrans could be used as a fluorescent fluid-phase markers to study cell permeability, endocytosis, or mechanisms of biomolecular delivery. The dextran conjugates are available in a variety of molecular weights, and contain a formaldehyde-fixable free-amine group. CF(R) dyes are Biotium's line of...
