JB-1
Based on 1 Customer Validation
JB-1, an IGF-I analog, is a selective IGF-I receptor inhibitor that does not interact with IGF-II. JB-1 competes with IGF-I for binding to IGF-1R and blocks receptor autophosphorylation. JB-1 increases the level of sVEGFR-1. JB-1 normalizes retinal abnormalities, including reducing retinal neovascularization. JB-1 is applicable to studies related to oxygen-induced retinopathy.
