Saddle River, NJ (PRWEB) May 13, 2010
Chromogenic substrates for immunoassays featuring prestained color and up to a 4 year shelf life are now available in North America from SeraCare Life Sciences. The company has expanded its offering by adding the full line of enzymatic substrates, buffers, and stabilizers developed by Kem-En-Tec, the premier manufacturer of immunoassay components in Europe. “Kem-En-Tec is an obvious partner for SeraCare,” says Tamara Smith, Senior Product Manager, SeraCare Life Sciences. “Our customers have been looking for the innovations that Kem-En-Tec brings to the table, such as long shelf life, fizzing, buffered tablets and prestained TMB substrates. Custom labeling and packaging is available, allowing us to serve not only scientists at the bench or using automation but also manufacturers developing diagnostic kits.”
A portfolio of the commonly used substrates, including TMB, pNPP and BCIP, is now available from SeraCare for colorimetric measurement employing alkaline phosphatase (AP) or horseradish peroxidase (HRP) probes. Ready for immediate use, these substrates are water based and contain no harmful solvents. Other popular substrates OPD, DAB, and AEC are supplied as fizzing, fast dissolving tablets. The liquid TMB substrate is available with a patented prestain, giving a red color that enhances visibility of the liquid during pipetting without interference to assay sensitivity.
Antibody and conjugate stabilizers allow for the dilution of critical components while enhancing the signal and stabilizing samples for long term storage without loss of activity. Blocking buffers for ELISA and Western blotting are BSA free. The reagents are manufactured in facilities compliant with current Good Manufacturing Guidelines under rigorous quality control. Bulk quantities and the ability to fill custom sizes are also available.
