GRADE & PURITYCarrier Free?Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays.Bioactive?Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure.ActiBioPure™?ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required.High Performance?High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short.PBS Only?PBS-only formulation — supplied in phosphate-buffered saline with no other additives. Use when you need a clean PBS buffer free of stabilizers/carriers.≥90%(SDS-PAGE)See COA

Recombinant Human IGF-I/IGF-1 Protein (rp156332) - Bioactivity Measured in a cell proliferation assay using MCF-7 cells. The ED50 for this effect is typically 28.6 ng/mL.
Recombinant Human IGF-I/IGF-1 Protein (rp156332) - SDS-PAGE 3 μg/lane of Recombinant Human IGF-I/IGF-1 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 10.2 & 13.8 kDa under reducing conditions and 10.4 & 13.8 & 20.9 kDa under non-reducing conditions. IGF-I/IGF-1 can form oligomers under certain conditions (PMID: 11551198).
