E coli Testing
MOLTOX Molecular Toxicology Inc E.Coli Mutagenicity Kit
The materials contained in this E. coli Mutagenicity Assay Kit include virtually all of the supplies necessary for the conduct of the assay as described by Green & Muriel, Mutat. Res. 38: 3, 1976. We strongly recommend that you carefully read this paper before you attempt to perform the assay. The MOLTOX E. coli kit contains two tester strains; WP2 trp (72-187L) and WP2 trp uvrA (72-188L). Each strain was constructed with a lesion (tryptophan mutation) in the tryptophan operon. WP2 uvrA also contains a lesion in a DNA repair-coding gene (uvrA) that increases sensitivity to certain mutagenic activities. The MOLTOX E. coli Mutagenicity Test kit includes sufficient components for testing 1 unknown sample, in triplicate analysis of 5 concentrations, positive and negative controls, with and without S9.
BioMed Diagnostics A selective and chromogenic medium for enterohemorrhagic E. coli O157. | Detects: enterohemorrhagic Eschericia coli O157 | Available in: 20 pack
A selective and chromogenic medium for enterohemorrhagic E. coli O157. COLOREX O157 is designed for simultaneous growth, observation and chromogenic differentiation of E. coli O157 from clinical or food specimens. This device makes preliminary detection easy by producing distinctive color differences between the growth of E. coli O157 as well as other organisms all while inhibiting the growth of mold, fungi, and other bacteria. | Detects: enterohemorrhagic E. coli O157. | Time to Result: Incubate 18-24 hours at 37C. | Available in: 20 pack

AdipoGen LPS from E. coli O8:K27 (S-form) TLRpure Sterile Solution
LPS from E. coli O8:K27 (S-form) TLRpure Sterile Solution, AdipoGen Life Sciences. Chemical. MW: . Isolated and purified from E. coli O8:K27. Activation of cells by LPS is mediated by the Toll-like receptor 4 (TLR4). For optimal interaction with LPS, TLR4 requires association with myeloid differentiation protein 2 (MD-2). According to current consensus activation of TLR4 is preceded by the transfer of LPS to membrane-bound (m) or soluble (s) CD14 by LPS-binding protein (LBP). Re-form LPS and lipid A, but not S-form LPS, are capable of inducing TNF-alpha responses also in the absence of CD14. LPS, synthesized by most wild-type (WT) Gram-negative bacteria (S-form LPS), consists of three regions, the O-polysaccharide chain, which is made up of repeating oligosaccharide units, the core oligosaccharide and the lipid A, which harbors the endotoxic activity of the entire molecule.

Best fluorogenic substrate developed for matrilysin (also called punctuated metalloproteinase 1, PUMP-1 or MMP-7) thus far. Besides good kinetic parameters (kcat/km= 1.9 x 105 M-1s-1), it presents good solubility in assay buffer.SEQUENCE: DNP-Arg-Pro-Leu-Ala-Leu-Trp-Arg-Ser-OH (trifluoroacetate salt)ONE-LETTER SEQUENCE: DNP-RPLALWRSMOLECULAR FORMULA: C52H77N17O14MOLECULAR WEIGHT: 1164.30STORAGE CONDITIONS: -20 5 CCAS REGISTRY NUMBER: [172666-82-9]SYNONYMS: MMP-7 Fluorogenic SubstrateRESEARCH AREA: CancerREFERENCES:A.R.
