Crovalimab
Based on 1 Customer Validation
Crovalimab (SKY59; RO7112689) is a novel humanized antibody against C5 in a pH-dependent manner with KDs of 15.2 nM and 16.8 μM at pH 7.4 and 5.8, respectively. Crovalimab binds human FcRn with great affinity (KD: 17 μM at pH 6.0). Crovalimab can block cleavage of C5 by the C5 convertase and inhibite the activity of a C5 variant (p.Arg885His). Crovalimab inhibits C5b-9 formation significantly in all three complement pathways, the classical pathway (CP), lectin pathway (LP), and alternative pathway (AP). Crovalimab has the potential for paroxysmal nocturnal hemoglobinuria (PNH) and complement-mediated diseases research.

Complement C5
Crovalimab (SKY59; RO7112689; 0-100 μg/mL) inhibits haemolysis in classical pathway and reactive lysis systems[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Crovalimab (20 mg/kg; iv; a single dose) stably suppressed complement activity in plasma for 8 weeks[1].
Crovalimab (5 mg/kg by iv at day 0 and 2 mg/kg by sc at day 7, 21, 35, 49, and 63) causes over 20% of serum hemolytic activity in the cRBC lysis assay to correlate with events such as dysphagia and dramatic increases in lactate dehydrogenase (LDH) and alanine aminotransferase (ALT) levels[1].

Immobilized Complement C5 Protein, Human (HEK293, His, HY-P700862) can bind Crovalimab. The EC50 for this effect is 5.406 ng/mL. -
Flow cytometric analysis of 1X106 HepG2 cells with Crovalimab (HY-P99965, red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then stained with the primary antibody at 1/50 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 kappa Isotype Control (HY-P99001, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
