Browse research-use secondary antibodies by host species, target species, conjugation, label type, and application. Find HRP, AP, biotin, FITC, PE, and fluorescent conjugates for ELISA, Western blot, IHC, IF, and flow cytometry.
Select the primary antibody host, target immunoglobulin species, conjugation label, and application to identify suitable secondary antibodies.
The conjugation label determines how the signal is detected. Choose HRP, AP, biotin, FITC, PE, or fluorescent labels according to the application, instrument, substrate, and detection workflow.
HRP secondary antibodies are commonly used for ELISA, Western blot, IHC, and chemiluminescent or colorimetric detection workflows.
Secondary antibodies are selected according to the species in which the primary antibody was raised. Use this compatibility grid to match anti-rabbit, anti-mouse, anti-goat, anti-rat, and anti-human secondary antibodies with the correct detection label.
If the primary antibody was raised in rabbit, select a secondary antibody that recognizes rabbit immunoglobulins, such as goat anti-rabbit IgG.
Browse secondary antibodies by target immunoglobulin, host species, conjugation label, cross-adsorption, application, and detection method.
HRP-conjugated secondary antibody for detection of rabbit primary antibodies in ELISA, Western blot, and IHC workflows.
FITC-conjugated secondary antibody for fluorescence microscopy and selected flow cytometry applications.
Biotinylated secondary antibody for streptavidin-based signal amplification in ELISA, IHC, and immunofluorescence workflows.
PE-conjugated secondary antibody for bright fluorescence detection in flow cytometry and cellular staining applications.
AP-conjugated secondary antibody for alkaline phosphatase-based colorimetric or chemiluminescent detection.
Send the primary antibody host, target species, application, sample type, and preferred detection label. We can help identify a suitable secondary antibody.
Request support →Secondary antibody selection depends on the primary antibody host, target species, conjugation label, application, detection instrument, substrate, and cross-reactivity requirements.
Identify the species of the primary antibody, such as rabbit, mouse, goat, rat, or chicken.
Select anti-rabbit, anti-mouse, anti-goat, anti-rat, anti-human, or anti-chicken reagents.
Choose HRP, AP, biotin, FITC, PE, or fluorescent labels according to the detection system.
Match the antibody to ELISA, WB, IHC, IF, flow cytometry, or imaging workflows.
HRP and AP are commonly selected for ELISA because they support colorimetric or chemiluminescent signal generation.
HRP-conjugated secondary antibodies are widely used for Western blot detection, especially with chemiluminescent substrates.
Fluorescent secondary antibodies are selected by excitation/emission profile, microscope filters, and multiplex panel design.
PE, FITC, and other fluorescent secondary antibodies are selected based on the cytometer laser and detector configuration.
Clear answers for selecting secondary antibodies by primary antibody host, target immunoglobulin, conjugation label, cross-adsorption, and application.
Choose a secondary antibody based on the host species of the primary antibody, the target immunoglobulin class, the conjugation label, the intended application, and whether cross-adsorbed specificity is required. For example, if your primary antibody is raised in rabbit, select an anti-rabbit secondary antibody.
Goat anti-rabbit IgG means the secondary antibody was produced in goat and is designed to recognize rabbit IgG. It is typically used to detect rabbit primary antibodies in ELISA, Western blot, IHC, IF, or other antibody-based methods.
HRP and AP conjugates are commonly selected for ELISA because they work with enzyme substrates to produce measurable colorimetric or chemiluminescent signals. Biotinylated secondaries can also be used with streptavidin-based detection systems.
Fluorescent secondary antibodies are used for immunofluorescence microscopy, imaging, and flow cytometry. Select the fluorophore according to the microscope filter set, flow cytometer laser, emission channel, and multiplex panel design.
Cross-adsorbed secondary antibodies are processed to reduce unwanted binding to immunoglobulins from other species. They are useful in multiplex staining, multi-species samples, and experiments where background or cross-reactivity must be reduced.
