特異性：Recognizes human IGSF4B.The IGSF4B ECD is highly conserved, sharing 95-96% aa identity between human mouse, rat, dog and cow sequences. The ECD of IGSF-4A, B, C and D proteins share 35-50% aa identity.
純度：Purified > 90%, as determined by SDS-PAGE and visualized by silver stain. Endotoxin: < 1.0 EU per 1ug of the protein as determined by the LAL method.
形状：Supplied as a lyophilized powder in PBS. Reconstitute with sterile PBS to a concentration of >100ug/ml. For long term storage a carrier protein (e.g. 0.1% HSA or BSA) should be added.
