GRADE & PURITYCarrier Free?Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays.Recombinant?Recombinant — produced via recombinant expression for defined sequence and consistency. Use for reproducible, animal-free proteins of known origin.Validated?Validated grade — performance confirmed in defined applications before release. Use when you want documented assurance the reagent works as stated.ExactAb™?ExactAb™ — Aladdin's antibody line emphasizing precision and validated quality. Use for reliable, specificity-validated antibody applications.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.≥95%(SDS-PAGE)See COA
