A21020 | HRP, Goat Anti-Rabbit IgG — The Rabbit Secondary That Delivers Stunning Signal-to-Noise (449 Publications Can't Be Wrong)

Rabbit Antibodies Are Everywhere — You Need a Secondary That Matches Their Quality

Rabbit polyclonal and monoclonal antibodies are among the most widely used primary antibodies in biomedical research—valued for their high affinity, broad epitope recognition, and exceptional performance in immunohistochemistry. But a great primary antibody is only half the equation. You need a secondary antibody that delivers clean, amplified signal without introducing background noise. Abbkine's HRP, Goat Anti-Rabbit IgG (A21020) is that secondary—cited in 449 publications and trusted by researchers across disciplines [1†L31].

Affinity Purified, HRP-Conjugated, Exceptionally Specific

A21020 is an affinity-purified polyclonal antibody raised in goat against rabbit IgG whole molecule [1†L4-L5]. It reacts with the heavy chains of rabbit IgG and the light chains of all other rabbit immunoglobulins, with no reactivity on non-immunoglobulin serum proteins [1†L27-L30]. The HRP conjugate provides robust signal amplification for even the most challenging targets.

Applications and Recommended Dilutions

Validated across three core applications with the following suggested starting dilutions [1†L5-L8]:

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

449 Publications — Including Nature Medicine, Science, and More

A21020 has been cited in 449 publications, including papers in Nature Medicine (IF: 50) on hepatic ischemia-reperfusion injury, Science (IF: 45.8) on base-modified nucleotides mediating immune signaling in bacteria, and Nature Microbiology (IF: 19.4) on plant commensal secretion systems [1†L31-L48]. When your rabbit primary antibody deserves the best secondary, this is the one.
