NF[kappa]B transcription factor assay kits

Description: These assays are non-radioactive methods for detecting specific transcription factor DNA binding activity in nuclear extracts and whole cell lysates. A specific dsDNA sequence containing the NF[kappa]B response element is immobilized on the bottom of the wells in a 96-well plate. The transcription factor is detected by the addition of a specific primary antibody. A colorimetric readout at 450 nm is obtained through a horseradish peroxidase-conjugated secondary antibody.

ELISA kits, femtoELISA™

Description: The femtoELISA™ kits utilise a non animal protein blocker, NAP-BLOCKER™ that minimises cross-reactivity with researcher's antigens and antibodies. For the detection of HRP, an improved, ultra sensitive, non volatile, stable colorimetric substrate based on tetramethyl benzidine (TMB) is supplied. Reagent does not require hydrogen peroxide that can have detrimental effects on many biological factors, which may ultimately affect the assays.

BCIP/TNBT substrat de phosphatase alcaline

Description: BCIP/TNBT Membrane Alkaline Phosphatase Substrate is an artificially manufactured chromogenic substrate for use in sensitive colorimetric assays. BCIP/TNBT can be utilized in ELISA, in situ hybridization, and IHC. Alkaline phosphatase hydrolyzes the BCIP to 5-bromo-4-chloro-3-indole, which is oxidized by oxygen in the atmosphere, yielding a blue dye. In the presence of TNBT, an insoluble dark blue precipitate is formed after a reduction reaction instead.

Bleu nitré-tétrazolium chlorure (NBT) ≥90% (par HPLC), Sigma-Aldrich®

Description: Nitrotetrazolium blue (NBT), in combination with BCIP (5-bromo-4-chloro-3-indolyl-phosphate), is required for the detection of labeled probes in western blots. It is part of the colorimetric detection assay. NBT and BCIP dyes detect alkaline phosphatase activity, thereby generating an insoluble purple dye (diformazan). The dye is visible at areas where the labeled probe has hybridised to its target.
