| Description | This product is a human monoclonal antibody that reacts with IGF1R. The antibody is expressed with mammalian cell transient expression system, serum-free and purified by affinity chromatography. The purity and integrity are tested via SDS-PAGE and SEC-HPLC analysis. Given an antigen, additional QC measures are also desired such as affinity testing and binding validation. Specifically, the antibody is provided in multiple formats for in vivo and in vitro assays. The Invivo version features greater than 95% purity, ultra-low endotoxin levels (<1 EU/mg or 0.1 EU/mg), and is preservative, stabilizer, and carrier protein-free. |

Figure 1 Anti-Human IGF1R Monoclonal Antibody (V3S-0622-YC4575) in SDS-PAGE
SDS-PAGE analysis of V3S-0622-YC4575 in non-reduced (lane 1) and β-mercaptoethanol-reduced (lane 2) conditions. Gel stained for 30 minutes with Coomassie Blue. As a result of different β-mercaptoethanol-reduced proteins (Heavy chain and Light chain) migrate as about 50 kDa and 25 kDa, respectively. And non-reduced protein migrates as 130-180 kDa.

ELISA analysis of V3S-0622-YC4575 was performed by coating with recombinant IGF1R protein (50 ng/mL). Then blocked with BSA, and incubated with IGF1R Antibody, V3S-0622-YC4575. The HRP-conjugated goat anti-human IgG as a secondary antibody. Detection was performed using TMB substrate and stopped with sulfuric acid. The absorbances were read on a spectrophotometer at 450 nm.
