AffiAB® Goat Anti-CD45 Polyclonal IgG Antibody

Our Goat Anti-CD45 Polyclonal IgG Antibody specifically targets the CD45 antigen for recognition and binding. Ideal for ELISA, Western Blot, and Immunohistochemical assays, this polyclonal antibody ensures reliable performance and accuracy.

Host: Goat
Species: Human

Goat anti-CD45 polyclonal IgG antibody is an antibody that specifically binds to CD45, also known as leukocyte common antigen (LCA). CD45 is a transmembrane protein that is widely expressed in all hematopoietic cells and is involved in signal transduction in immune cells. It plays a crucial role in the activation and proliferation of T and B lymphocytes, and its expression is used to distinguish between lymphoid and myeloid cells. Goat anti-CD45 polyclonal IgG antibody is commonly used as a tool in research to detect and analyze CD45 expression in cells.

Goat Anti-CD45 Polyclonal IgG Antibody

The Goat Anti-CD45 Polyclonal IgG Antibody has emerged as a pivotal tool in immunological research. CD45, a transmembrane protein tyrosine phosphatase, is widely recognized as a critical marker for leukocytes (white blood cells) and plays a significant role in cell-mediated immune responses. This antibody's ability to specifically target CD45 has profound implications in research areas spanning from immunology to hematological diseases.

Understanding Goat Anti-CD45 Polyclonal IgG Antibody

Production and Specificity:

This antibody is generated by immunizing goats with a portion of the CD45 antigen. The resulting polyclonal IgG antibodies have the capacity to recognize multiple epitopes on CD45, enhancing detection sensitivity and specificity. This polyclonality is advantageous for comprehensive detection in various experimental contexts.

Benefits of Goat-Derived Antibodies:

Goats, as a source for antibody production, offer several benefits including high antigen sensitivity and substantial antibody yields. Their broad immune response is particularly effective for producing antibodies against diverse antigens, like CD45, which may exhibit variations in different cell types or species.
