GRADE & PURITYAnimal Free?Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material.Carrier 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.≥95%(SDS-PAGE)expressed in HEK293; See COA

Recombinant Human Efgartigimod alfa Protein (rp302524) - SDS-PAGE
3 μg/lane of Recombinant Human Efgartigimod alfa Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 31.0 kDa under reducing conditions and 51.4 kDa under non-reducing conditions.
Fc fusion proteins can be linked by disulfide bonds in the Fc hinge region to form stable dimers (PMID: 23665380).
