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.His Tag?His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein.PBS Only?PBS-only formulation — supplied in phosphate-buffered saline with no other additives. Use when you need a clean PBS buffer free of stabilizers/carriers.≥90%(SDS-PAGE)See COA

Mecanismos bioquímicos y fisiológicos
Transferrin is a glycoprotein with an approximate molecular weight of 76.5 kDa. This glycoprotein is thought to have been created as a result of an ancient gene duplication event that led to generation of homologous C and N-terminal domains each of which
