Recombinant CD19 Antibody - Primary antibody, specific to CD19

Cat. No.: Ab210975
AVAILABLE TO ORDER
GRADE & PURITY Animal 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. 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. 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. ≥95%(SDS-PAGE) See COA
