Our anti-rabbit secondary antibodies are affinity-purified polyclonal or monoclonal antibodies with well-characterized specificity for rabbit immunoglobulin classes and fragments. They are available in host species including goat, donkey, mouse, chicken, and sheep. Our anti-rabbit secondary antibodies also come in a variety of conjugates:
- Unlabeled antibodies
- Enzyme conjugates (alkaline phosphatase (AP) or horseradish peroxidase (HRP))
- Fluorescent conjugates (Alexa Fluor, Fluorescein (FITC), and other classic fluorescent conjugates
Anti-rabbit secondary antibodies are generated by immunizing a host animal with a pooled population of immunoglobulins (Ig) from the target species. In this case, the Ig would come from rabbits and be introduced into one of the available host species: goat, donkey, mouse, chicken, or sheep. After the host animal’s immune system has responded to the rabbit Ig, the resulting antibodies are collected and purified.
Our anti-rabbit secondary antibodies are available as whole IgG or the F(ab')2 fragment. Each of these antibodies is affinity purified using its target antigen (the primary antibody class and fragment) coupled to an agarose support. This affinity purification helps eliminate cross-reactivity from nonspecific proteins, resulting in high specificity and low background signal. Conjugated antibodies are affinity purified before labeling.
Selected secondary antibodies have been further purified by adsorbing the antigen-purified antibody to an affinity column containing immobilized serum proteins or IgG of selected species. This additional processing minimizes antibody cross-reactivity to the serum proteins of those selected species. These antibodies are designated as cross-adsorbed or highly cross-adsorbed, based on the amount of processing that has occurred.

HeLa cells were treated with 60 µM chloroquine overnight. The following day, cells were fixed and permeabilized and subsequently labeled with 1 µg/mL anti-LC3B with Invitrogen Goat anti-Rabbit Secondary Antibody, Alexa Fluor 488 green (Cat. No. A-11034). Cells were counterstained with Invitrogen HCS Cellmask Deep Red (purple) and 1 µg/mL Hoechst 33342 (blue) stains. Cells were imaged on a Nikon D200 wide-field microscope.
Immunohistochemistry using Invitrogen NMDA Receptor Subunit 2A Polyclonal Antibody, Rabbit: rat brain cryosections labeled with anti–NMDA receptor, subunit 2A (rat) antibody, rabbit IgG fraction (Cat. No. A6473) and detected using Invitrogen Goat anti-Rabbit IgG Secondary Antibody, Alexa Fluor 488 conjugate (Cat. No. A11008). The tissue was also labeled with Invitrogen GFAP / Glial Fibrillary Acid Protein Antibody, Alexa Fluor 594 conjugate (Cat. No. A21295) and counterstained with Invitrogen TOTO-3 iodide (Cat. No. T3604), which was pseudocolored light blue in this image.
Immunofluorescence analysis of neurons using Invitrogen anti-beta III tubulin antibody (Cat. No. 480011). GABAergic precursor cells derived from H9 embryonic stem cells were differentiated for 7 days and stained with antibodies against GABA (Cat. No. PA5-32241 at 1:5,000) followed by Invitrogen Donkey anti-Rabbit IgG (H+L) Secondary Antibody, Alexa Fluor 488 conjugate (Cat. No. A21206, green) and neuronal marker beta III tubulin (Cat. No. 480011 at 1:1,000) followed by Invitrogen Goat anti-Mouse IgG Secondary Antibody, Alexa Fluor 594 conjugate (Cat. No. A11005, red). Nuclear DNA was stained with DAPI (blue).
