Application Notes:

Clone G7 binds to Thy-1 epitope region A and also recognizes Thy-1.1/CD90.1 and Thy-1.2/CD90.2 alloantigens. Additional reported applications (for the relevant formats) include: in vitro T-cell activation1,3-4,6, induction of apoptosis2,5, and immunohistochemical staining7,8 of zinc-fixed paraffin-embedded sections and acetone-fixed frozen sections.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

CD90 is a 25-35 kD immunoglobulin superfamily member, also known as Thy-1. It is expressed on hematopoietic stem cells and neurons, all thymocytes, and peripheral T cells, but not on B cells. CD90 is a glycosylphosphatidylinositol (GPI)-anchored membrane glycoprotein involved in signal transduction. CD90 is involved in costimulation of lymphocyte proliferation and activation, and hematopoietic stem cell differentiation. CD90 has been shown to interact with CD45. The G7 antibody is able to stimulate T cell proliferation and IL-2 secretion and induce apoptosis of thymocytes and CTL clones.
