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).
SDF1 / CXCL12
SDF-1 gamma Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 99 amino acids and having a molecular mass of 11.6kDa.The SDF-1g is purified by proprietary chromatographic techniques.
Greater than 96% by SDS-PAGE and HPLC
Lyophilized from PBS, pH 7.4.
Store at -20°C lyophilized. Once reconstituted: Store at -20°C. Aliquot to avoid freeze-thaw cycles.
Chemoattractant active on T-lymphocytes, monocytes, but not neutrophils. Activates the C-X-C chemokine receptor CXCR4 to induce a rapid and transient rise in the level of intracellular calcium ions and chemotaxis. Also binds to atypical chemokine receptor ACKR3, which activates the beta-arrestin pathway and acts as a scavenger receptor for SDF-1. SDF-1-beta(3-72) and SDF-1-alpha(3-67) show a reduced chemotactic activity.
