Product Description
The BioDeviceLab Donkey Anti-Goat IgG (H+L) Secondary Antibody is a purified polyclonal antibody raised in donkey and directed against both the heavy and light chains of goat immunoglobulin G. By recognizing the conserved regions of goat IgG, this secondary antibody enables reliable detection and amplification of signals generated by goat primary antibodies across a wide range of biological targets.
Secondary antibodies play a central role in immunoassays by amplifying primary antibody signals, improving sensitivity, and enabling flexible assay design through indirect labeling strategies. This antibody is suitable for use with fluorescent, enzymatic, or custom-conjugated detection systems and is compatible with standard fixation and staining protocols.
The antibody is formulated to perform consistently in traditional cell culture assays as well as advanced applications including organoids, 3D cultures, tissue engineering constructs, and microfluidic or organ-on-chip platforms. Its broad compatibility makes it well suited for imaging-based studies, multiplexed assays, and biodevice validation workflows.
