Mouse IgG2a-kappa, anti-Spike RBD - Isotype Control Antibody, specific to Spike RBD, Mouse IgG2a

Cat. No.: Ab139747
COA
Mouse IgG2a-kappa, anti-Spike RBD - by Aladdin Scientific
AVAILABLE TO ORDER
GRADE & PURITY 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. Low Endotoxin ? Low-endotoxin grade — endotoxin reduced to low controlled levels. Use in sensitive biological work where high endotoxin would interfere. Azide Free ? Azide-free — without sodium azide preservative. Use in conjugations, cell work, or assays where azide is toxic or inhibitory. ≥95%(SDS-PAGE&SEC-HPLC) See COA
