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".
ASS1 Recombinant Human produced in E.Coli is a single, non-glycosylated polypeptide chain containing 432 amino acids (1-412 a.a.) and having a molecular mass of 48.6 kDa. The ASS1 is fused to 20 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques.

Arginosuccinate synthetase catalyzes the penultimate step of the arginine biosynthetic pathway. There are approximately 10 to 14 ASS pseudogenes scattered across the human genome; the ASS gene located on chromosome 9 appears to be the only functional gene for argininosuccinate synthetase. The ASS primary transcript is subject to alternative splicing in the 5' non-coding region; a splice variant lacking exon 2 occurs in liver and fibroblast cells.
