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.His Tag?His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein.≥95%(SDS-PAGE)See COA

Biochemical and Physiological Mechanisms
Apolipoprotein E (ApoE) is a 34.2 kDa glycosylated protein with 299 amino acid residues. There are three isoforms in human (apoE2, apoE3, and apoE4) due to different amino acid residues at positions 112 and 158. ApoE is synthesized predominantly in the li
