Rat IgG1-kappa - Isotype Control Antibody, Rat IgG1

Cat. No.: Ab141776
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. 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

Overview

Rat IgG1 isotype control-InVivo monoclonal antibody (Clone: HRPN) reacts with horseradish peroxidase (HRP). Because HRP is not expressed by mammals this antibody is ideal for use as an isotype-matched control for rat IgG1 antibodies in most in vivo and in vitro applications.
