Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to
worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting
immunostaining in relation to complex human pathologies.
TCR Screening Services
Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding.
Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".
This kit recognizes natural and recombinant Human CREB.
LS-F21999 is a 96-well enzyme-linked immunosorbent assay (ELISA) for the Quantitative detection of Human CREB1 / CREB in samples of Plasma and Serum. It is based upon a Sandwich assay principle and can be used to detect levels of CREB1 / CREB as low as 0.188 nanograms per millilter.
Colorimetric - 450nm (TMB)
0.313 - 20 ng/ml
Intra-Assay: CV<10% Inter-Assay: CV<10%
Due to their limited shelf life, LSBio ELISA kits are not typically stocked as finished goods. Upon receipt of an order each kit is assembled and tested to ensure that it meets specifications before shipping. Minor changes may occur to the Range, Sensitivity, and Precision. In the event of a significant change the order would be confirmed with the customer before shipping ELISA kit lot numbers reflect the date of final assembly and testing for each specific kit rather than a bulk manufactured lot. All kits are tested to confirm that they fall within their defined Inter- and Intra- assay coefficient of variation.

CREB (cAMP response element binding protein1), a DNA binding protein, is a member of the leucine zipper family of transcription factors. CREB interaction with DNA requires phosphorylation at Ser 119 by activated cAMP protein kinase A. Once phosphorylated CREB binds to an 8 base enhancer know as the cAMP response element (CRE) containing a conserved core sequence TGACG. CREB also interacts with CBP (CREB binding protein) and RNA polymerase II when phosphorylated on Ser 133.
