Purity: > 95% by SDS - PAGE Format: Liquid. 20mM Tris-HCl buffer (pH8.0) containing 20% glycerol, 0.1M NaCl, 1mM DTT. CRIPT, also known as cysteine-rich PDZ-binding protein, is involved in the cytoskeletal anchoring of DLG4 in excitatory synapses. Recombinant human CRIPT protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography.
