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.Azide Free?Azide-free — without sodium azide preservative. Use in conjugations, cell work, or assays where azide is toxic or inhibitory.High Performance?High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short.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)

Images
Recombinant Human VSIG4 Protein (rp164797) - SDS-PAGE 3 μg/lane of Recombinant Human VSIG4 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the band at 48 kDa. The protein has a calculated MW of 30 kDa. The protein migrates as 48 kDa under reducing (R) and non-reducing (N) conditions (SDS-PAGE) due to glycosylation.
