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".
Purified / Lyophilized / Biologically Active / Endotoxin Level: Less than 0.1 ng/µg of protein (less than 1EU/µg).
BTC / Betacellulin
Betacellulin Bovine Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 80 amino acids and having a molecular mass of 9003 Dalton. Betacellulin Bovine Recombinant is purified by proprietary chromatographic techniques.
Greater than 95% by SDS-PAGE and HPLC
The ED50, calculated by the dose-dependent proliferation of murine BALB\C 3T3 cells (measured by 3H-thymidine uptake) is < 10.0 ng/ml, corresponding to a Specific Activity 100,000 units/mg.
Lyophilized from 50 mM acetic acid.
Reconstitute with distilled water. It is not recommended to reconstitute to a concentration less than 100 ug/ml.
Lyophilized powder may be stored at -20°C. Reconstituted product is stable for 1 year at -20°C. Add 0.1% HSA or BSA for long term storage.
