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".
Human GRB2 Protein (Recombinant 6His,C-terminus) (Met1-Val217) - LS-G39563
E. coli Expression System
Purified / Lyophilized / Endotoxin Level: Less than 1.0 EU/µg protein (determined by LAL method).
Recombinant Human GRB2 is produced by our E. coli expression system and the target gene encoding Met1-Val217 is expressed with a 6His tag at the C-terminus.
Greater than 95% by SDS-PAGE
Less than 1.0 EU/µg protein (determined by LAL method).
Lyophilized from 0.2 µm filtered 20 mM Tris-HCl, pH 8.0, 150 mM NaCl.
Reconstitute in sterile distilled water not less than 100 µg/ml. This solution can then be diluted into other aqueous buffers
Lyophilized protein should be stored at less than -20°C. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at less than -20°C for 3 months.
Adapter protein that provides a critical link between cell surface growth factor receptors and the Ras signaling pathway.Isoform 2 does not bind to phosphorylated epidermal growth factor receptor (EGFR) but inhibits EGF-induced transactivation of a RAS-responsive element. Isoform 2 acts as a dominant negative protein over GRB2 and by suppressing proliferative signals, may trigger active programmed cell death.
