PTP 1B protein

• Catalog Number: orb533679
• Category: Proteins
• Description: PTP 1B is the prototype nontransmembrane protein tyrosine phos-phatase. It is a ubiquitous protein that was originally identified in human placenta. This highly active enzyme is well suited for the study of tyrosine phosphatase kinetics and substrate specificity, as well as for the screening of inhibitors.
