Cygnus Technologies E. coli Host Cell DNA Detection Kit in Tubes
This method utilizes a 2 ml microfuge tube format to measure residual E. coli host cell DNA. The kit includes our proprietary extraction procedure, which isolates residual DNA without the use of iodine or glycogen.The superior co-precipitating reagents do not interfere with qPCR and ensure that pellets do not become dislodged during the extraction procedure. This eliminates the need to centrifuge samples again as well as the need to retest or repeat a run. Cell line-specific E. coli DNA calibrators are included, and upon completion of extraction, samples are reacted with PicoGreen solution. Time to completion is under 2 hours. Each kit supplies enough reagent for the analysis of 50 samples in duplicate.
CPC Scientific DNP-Arg-Pro-Leu-Ala-Leu-Trp-Arg-Ser-OH (trifluoroacetate salt) 1MG
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.

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.
