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.High Performance?High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short.Fc tag?Fc tag grade — recombinant protein bearing a Fc tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein. The Fc tag aids dimerization and protein-A/G capture.≥95%(SDS-PAGE)

Bioactivity
Measured by its ability to inhibit neurite outgrowth of dissociated E13 chick embryonic dorsal root ganglia (DRG) neurons. When immobilized as a 3 µL droplet containing 200 ng on a nitrocellulose coated microplate, Recombinant Human MAG/Siglec 4a Fc Chimera is able to significantly inhibit neurite outgrowth.
