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.

Foire aux questions
What is the purity of this product, and how is it determined?
This product is supplied at ≥95% purity, determined by SDS-PAGE. Lot-specific values are stated on the Certificate of Analysis.
What does Animal Free mean?
Animal Free indicates that the material has been processed and tested for specialty industrial processing. Specifications focus on the impurities that affect performance in that application — for example, metal content for electronics, particle size for batteries, refractive index for optics, or moisture content for moisture-sensitive processes.
What does Carrier Free mean?
Carrier Free indicates that the material has been processed and tested for specialty industrial processing. Specifications focus on the impurities that affect performance in that application — for example, metal content for electronics, particle size for batteries, refractive index for optics, or moisture content for moisture-sensitive processes.
How should this product be stored?
Store at ?20 °C. Avoid repeated freeze–thaw cycles. Aliquot into single-use volumes before freezing.
How is this product shipped?
This product ships in an insulated container with ice pads. Unpack on arrival and transfer it to the storage condition stated above.
