CAS: 509077-98-9 Cat. No.: Ab175489
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. 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. ≥90%(SDS-PAGE&SEC-HPLC) See COA

Overview

Catumaxomab (anti-CD3&EpCAM), a trifunctional IgG2 antibody, is composed of mouse and rat heavy and light chains and binds to human EpCAM and human CD 3 receptors. The Fc region of Catumaxomab (anti-CD3&EpCAM) region has binding affinity for FcγR1 (CD 64), FcγRIIA (CD 32a), and FcγRIII (CD 16). Catumaxomab (anti-CD3&EpCAM) can be used for anti-tumor research, especially epithelial cancers.
