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 1.0 EU/µg protein (determined by LAL method).
PBK / TOPK
PBK Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 346 amino acids (1-322 a.a) and having a molecular mass of 38.6kDa (Molecular weight on SDS-PAGE will appear higher).PBK is fused to a 24 amino acid His-tag at N-terminus and purified by proprietary chromatographic techniques.
Greater than 95% by SDS-PAGE
20 mM Tris-HCl, pH 8.0, 20 mM DTT, 10% glycerol, 20 mM NaCl.
Store lyophilized at 4°C. Once reconstituted, aliquot and store at -20°C. Avoid freeze-thaw cycles.
TOPK is a TOPK protein kinase which may be associated with cell signaling in lymphokine-activated killer T (T-LAK) cells and spermatogenesis. Studies suggest that mitotic phosphorylation is required for its catalytic activity. Similar to MEK3/MAP2K3 and MKK6/MAP2K6, activated TOPK phosphorylates the MAP kinase p38. At least two mRNA variants have been identified - a major full-length form and a minor spliced form at the 5'-site, both encoding the same protein.
