Anti-Mouse IgD (Clone 11-26c.2a) – Purified No Carrier Protein

This monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added.

Liquid

Purified antibodies are manufactured in an animal free facility using only in vitro protein free cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates.

This antibody may be stored sterile as received at 2-8°C for up to one month. For longer term storage, aseptically aliquot in working volumes without diluting and store at -80°C. Avoid Repeated Freeze Thaw Cycles.

Clone 11-26c.2a specifically reacts with the delta heavy chain of mouse IgD, without cross- reacting with other classes of mouse immunoglobulin like IgA, IgG, or IgM.

Immunoglobulin D (IgD) is one of the five main classes of immunoglobulins. Though it is an antibody that is not well understood, it has been discovered to have a vital role in both innate and adaptive immunity. It aids in activating and regulating B cells, especially in the upper respiratory mucosa. In this location, it enhances immune surveillance and defense against respiratory pathogens¹. IgD also helps maintain a healthy microbiome by equipping myeloid effector cells with IgD antibodies that react to mucosal antigens, including both commensal and pathogenic microbes².

The 11-26c.2a clone is an essential tool in immunology research, particularly in the study of B cell development and activation pathways. It is widely used in flow cytometric analysis to identify surface IgD expression on mouse B cells. This provides valuable insights into B cell populations and their roles in immune responses^3,4. When the antibody is conjugated, it allows for easy detection and multiplexing in flow cytometry, enabling comprehensive immunophenotyping studies^5,6.

IgD is expressed by peripheral mature B cells.
