A21030 | HRP, Rabbit Anti-Goat IgG — The Goat Secondary That Completes Your Antibody Toolkit (23 Publications and Rising)

Goat Primaries Deserve a Secondary That Recognizes Them Perfectly

Goat primary antibodies are workhorses in many research applications—particularly in immunology, where goat anti-mouse or anti-rabbit antibodies are often used as primary reagents in sandwich ELISA and other detection systems. But finding a high-quality secondary antibody that recognizes goat IgG with high specificity can be surprisingly challenging. Abbkine's HRP, Rabbit Anti-Goat IgG (A21030) fills that gap with affinity-purified precision and HRP-conjugated sensitivity.

Affinity Purified, HRP-Conjugated, Goat-Specific

A21030 is an affinity-purified polyclonal antibody raised in rabbit against goat IgG whole molecule [7†L4-L5]. It reacts with the heavy chains of goat IgG and the light chains of all other goat immunoglobulins, with no reactivity on non-immunoglobulin goat serum proteins [7†L27-L30]. The HRP conjugate delivers 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 [7†L5-L8]:

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