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".
HS3ST1 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 310 amino acids (21-307 a.a) and having a molecular mass of 36.2kDa.HS3ST1 is fused to a 23 amino acid His-tag at N-terminus and purified by proprietary chromatographic techniques.

HS3ST1 Protein, 3OST1 Protein, 3-OST-1 Protein, 3OST Protein, H3-OST-1 Protein
Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) to catalyze the transfer of a sulfo group to position 3 of glucosamine residues in heparan. Catalyzes the rate limiting step in the biosynthesis of heparan sulfate (HSact). This modification is a crucial step in the biosynthesis of anticoagulant heparan sulfate as it completes the structure of the antithrombin pentasaccharide binding site.
