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".

Specificity and Use
TCF7 antibody was raised against synthetic peptide from N-Terminus of human TCF7 (P36402-9). Percent identity by BLAST analysis: Human, Chimpanzee, Orangutan, Monkey, Galago, Mouse, Elephant, Panda, Bovine, Guinea pig (100%); Opossum (92%); Marmoset, Rat, Hamster, Pig, Medaka, Zebrafish (85%).
Human TCF-1 / TCF7
Lyophilized from PBS, 2% sucrose.
50 µl Distilled water
Long term: -20°C, the use of 50% glycerol is recommended if storing aliquots in -20°C for long term use (up to 1 year); Short term (less than one week): +4°C. Avoid repeat freeze-thaw cycles.
Transcriptional activator involved in T-cell lymphocyte differentiation. Necessary for the survival of CD4+ CD8+ immature thymocytes. Isoforms lacking the N-terminal CTNNB1 binding domain cannot fulfill this role. Binds to the T-lymphocyte-specific enhancer element (5'-WWCAAAG-3') found in the promoter of the CD3E gene. May also act as feedback transcriptional repressor of CTNNB1 and TCF7L2 target genes. TLE1, TLE2, TLE3 and TLE4 repress transactivation mediated by TCF7 and CTNNB1.
