BD, 551543, Purified Rat Anti-Pig γδ T Lymphocytes MAC320

The MAC320 antibody monoclonal antibody specifically binds to the 270- and 280-kDa isoforms of the SWC6 heterodimer expressed on Null T cells. These cells form a unique population of CD2-, surface Ig-, and thymus-dependent nylon wool-nonadherent peripheral blood lymphocytes found at high frequencies in young pigs. Null T cells are also CD4- and CD8-, and the majority of them express γδ T-cell receptors (TCR). In addition to peripheral blood, MAC320+ leukocytes (CD2- γδ T cells) are found in the thymus, especially in the medulla and in the marginal zone and red pulp of the spleen. They are rare in normal lymph nodes, tonsils, Peyer's patches, bone marrow, and skin. An additional population of MAC320- CD2+ γδ T cells is found in the blood and spleen. The MAC320 antibody does not react with pig erythrocytes, monocytes, or granulocytes, nor with cow, sheep, or human lymphocytes.

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. Store undiluted at 4°C.
1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
3. Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.
4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
