Etrolizumab
Based on 2 publication(s) in Google Scholar
Etrolizumab (rhuMAb Beta7) is a gut-selective, anti-β7 integrin monoclonal antibody. Etrolizumab is specific targeting of the β7 subunit of α4β7 and αEβ7 integrins with Ki values of 18 nM and 1800 pM for Human α4β7 and Human αEβ7-293, respectively. Etrolizumab can be used in research of inflammatory bowel disease (IBD).

Etrolizumab (rhuMAb Beta7) binds the β7 subunit of both α4β7 and αEβ7 integrins with high affinity, with Kd values of 18 nM, 1800 pM, 181 pM, 116 pM, 57 pM, 31.7 pM, and 25.7 pM for Human α4β7, Human αEβ7-293, Mouse α4β7-38C13, Human α4β7-293, Rabbit PBLs, Human PBLs, and Cyno PBLs, respectively[1].
Etrolizumab (RPMI 8866 cells and αEβ7-293 cells) blocks the interaction of α4β7 with its cognate ligands MAdCAM-1 and VCAM-1 with IC50 values of 0.075 and 0.089 nM, respectively, and blocks the interaction between αEβ7 and its ligand E-cadherin with an IC50 value of 3.96 nM[1].

Flow cytometric analysis of 1X106 Jurkat cells with Etrolizumab (HY-P9984, red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Alexa Fluor 488-conjugated AffiniPure Goat Anti-Human IgG H&L (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG1(D356E/L358M) kappa Isotype Control (HY-P990100, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
