Ultrasensitive Cell Proliferation Assay Kit, Fluorogenic
A highly sensitive, reliable cell proliferation assay utilizing Calcein-AM, a fluorescent probe for staining viable cells (Ex.: ~485 nm; Em.: ~520 nm). For optimal results serum-free media or Dulbecco’s PBS is recommended. Endogenous esterases in serum can lead to increased blank values which can be subtracted out. Extremely useful for cytotoxicity assays.

Product Overview
Product Name: TMB, Ultrasensitive
Alternate Name/Synonyms: 3,3′,5,5′-Tetramethylbenzidine; TMBUS
Description: 3,3’5,5′-Tetramethylbenzidine (TMB) has been shown to be a safe-sensitive substrate for the assay of horseradish peroxidase (HRP). Initially, in the presence of HRP and hydrogen peroxide, a one-electron oxidation product is formed. This compound, a cation free radical, is blue in color with an adsorption maximum at 653 nm. Further reaction with HRP/H₂O₂ or acidification of the radical with acid yields the diimine terminal oxidation product adsorbing light at 450 nm. The extinction coefficient of the radical (E653 nm = 3.9 x 10⁴ mo⁻¹1 cm⁻¹) and diimine (E450 nm = 5.9 x 10⁴ mol⁻¹ cm⁻¹) provide a remarkably sensitive system for the assay of HRP and HRP labeled probes. TMBUS, available from Biovision Inc., is a single component reagent stable at room temperature and not sensitive to normal laboratory light. It is optimized with respect to TMB and hydrogen peroxide concentrations and yields a linear response with the concentrations of HRP usually employed in immunologic assays.
