A21040 | HRP, Goat Anti-Rat IgG — The Rat Secondary That Delivers Clean Data (14 Publications and Growing)

Rat Models, Rat Antibodies — You Need a Secondary That Speaks Rat

Rat models are indispensable in biomedical research—from toxicology and pharmacology to neuroscience and immunology. But when your primary antibodies come from rat, you need a secondary antibody that recognizes rat IgG with high specificity and minimal cross-reactivity. Abbkine's HRP, Goat Anti-Rat IgG (A21040) delivers exactly that: affinity-purified, HRP-conjugated detection for rat primary antibodies.

Affinity Purified, HRP-Conjugated, Rat-Specific

A21040 is an affinity-purified polyclonal antibody raised in goat against rat IgG whole molecule [2†L4-L5]. It reacts with the heavy chains of rat IgG and the light chains of all other rat immunoglobulins, with no reactivity on non-immunoglobulin rat serum proteins [2†L27-L29]. The HRP conjugate provides robust signal amplification for ELISA, Western blot, and IHC applications.

Applications and Recommended Dilutions

Validated across three core applications with the following suggested starting dilutions [2†L5-L8]:

• Western Blot: 1:10,000–1:100,000
• IHC-P: 1:500–1:2,000
• ELISA: 1:5,000–1:100,000
