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)

Recombinant Human Apolipoprotein E3 Protein (rp142912) - SDS-PAGE 2 μg/lane of Recombinant Human Apolipoprotein E3 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the band at 30 - 36 kDa under reducing conditions and 30 - 36 & 80 kDa under non-reducing conditions. APOE exists as multiple glycosylated and sialylated glycoforms within cells and in plasma (PubMed:29516132). The protein has a calculated MW of 35 kDa. The protein migrates as 30 - 36 kDa under reducing (R) condition due to glycosylation.
Recombinant Human Apolipoprotein E3 Protein (rp142912) - Binding Activity Immobilized Recombinant Human Apolipoprotein E3 Protein (rp142912) at 5 μg/mL can bind Recombinant Human TREM2 Protein with the EC₅₀ of 71.16 ng/mL.
