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".
Streptococcus Protein G Protein (Recombinant) (aa190-384) - LS-G19805
E. coli Expression System
Purified / Lyophilized
Recombinant streptococcal protein G lacking the albumin binding region thereby avoiding undesirable reactions with albumin, though the Fc binding domain is still present. The recombinant Protein G is produced in Escherichia coli using sequence from Streptococcus C1-C2-C3. The Protein G contains 196 amino acids (190-384) having a molecular mass of 21.6 kDa. The Protein-G migrates on SDS-PAGE around 32 kDa.
Greater than 95% by SDS-PAGE and HPLC
Lyophilized. No additives.
Reconstitution with deionized water or PBS.
Store at -20°C lyophilized. Once reconstituted: Store at -20°C. Aliquot to avoid freeze-thaw cycles.
