Mouse anti Pig CD4 Alpha

Description:

Mouse anti porcine CD4 alpha, clone MIL17 recognizes a ~55 kDa porcine homologue to the human CD4 antigen found on the surface of helper-T cells. MIL-17 was confirmed as a member of the CD4 alpha cluster at the ‘Third International Workshop on Swine Leukocyte Differentiation Antigens’. Porcine CD4 is a type 1 trans-membrane member of the immunoglobulin superfamily.

Pigs appear unusual amongst mammalian species as they appear to have four populations of resting T lymphocytes. In addition to the two populations of mutually exclusive CD4⁺/CD8^- and CD4^-/CD8⁺ lymphocytes, they also appear to have significant populations of CD4^-/CD8^- and CD4⁺/CD8⁺ cells. Lymphoblasts with a double positive phenotype have been described in other species but this is not the case for mature T lymphocytic calls.

Mouse anti pig CD4 alpha, clone MIL17 stains a population of cells with characteristic lymphocyte morphology in immunohistochemistry.
