- Highly specific
Poly-(Glu,Tyr) (4:1) is a random copolymer which has been shown to be a substrate for tyrosine-specific protein kinases. Poly-(GT)-biotin may be used with Streptavidin-XL665 and Anti-phosphotyrosine-cryptate for easily optimized HTRF® tyrosine kinase assays. HTRF enables to perform assay at physiological ATP concentrations.
