Rat IgG - Isotype Control Antibody, IgG

Cat. No.: Ab141774
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. 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. 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% See COA

Rat IgG (Ab141774) - ELISA
Rat IgG (Ab141774) was tested by ELISA. The plate was coated with 1.0 μg/mL Rat IgG. A serial dilution of Goat Anti-Rat IgG H&L Antibody (Biotin) was used as the secondary antibody. A HRP-streptavidin (np156148) was used at 1/20000 dilution for this ELISA.

Rat IgG (Ab141774) - SDS-PAGE
3 μg/lane of Rat IgG (Ab141774) was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining. Showing the band at 26.0 kDa (Light Chain) & 51.4 kDa (Heavy Chain), under reducing conditions; 164.3 kDa, under non-reducing conditions. The purity of the Rat IgG is greater than 95%.
