Collection: Secondary Antibodies

Secondary Antibodies — contains secondary antibodies that recognize immunoglobulins of specific species such as chicken IgY, human IgG, and mouse IgM, generally polyclonal antibodies from goats or sheep. This group functions as an indirect detection tool in various immunological techniques based on antigen-antibody binding.

Secondary Antibodies are used by molecular biology and immunology researchers in western blot, ELISA, and immunohistochemistry techniques to detect primary antibodies that have bound to the target antigen. Conjugates with HRP enzyme, biotin, or fluorophores such as FITC enable signal visualization colorimetrically or fluorescently, facilitating protein quantification in tissue samples or cell lysates.

Example products in this collection: TCI A3277 Anti-Human IgG Fc C-terminus Monoclonal Antibody, TCI G0386 Goat Anti-Mouse IgG (1mg/vial), TCI S0999 Sheep Anti-Chicken IgY HRP Conjugate, TCI G0387 Goat Anti-Mouse IgG Biotin Conjugate (0.1mg/vial), TCI S0998 Sheep Anti-Chicken IgY, TCI G0388 Goat Anti-Rabbit IgG (1mg/vial), TCI H1619 Sheep Anti-Chicken IgY Biotin Conjugate, TCI G0406 Goat Anti-Mouse IgG FITC Conjugate.

Make sure the species of the primary antibody matches the target recognized by the secondary antibody, pay attention to the conjugate type (enzyme, biotin, or fluorophore), as well as the package form and stock solution concentration. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.

Other categories at the same level under Antibodies, often used together in one laboratory workflow:

• Primary Antibodies [Life Science]
• Antibody Supplementary Products

This collection is further divided into 3 more specific groups:

• Anti-Mouse IgM
• Anti-Chicken IgY
• Anti-Human IgG
