Technical Data
CD3, a member of the immunoglobulin superfamily of cell surface receptors, is comprised of five invariable chains ranging from 16-28kD and is closely associated with the T cell antigen receptor (TCR). CD3 is expressed on 70-80% of normal peripheral blood lymphocytes and on 10-20% of thymocytes. It plays a major role in signaling during antigen recognition, leading to T cell activation.

Suitable for use in Flow Cytometry, Immunohistochemistry, Immunoprecipitation and In vitro activation. Other applications have not been tested.

Recommended Dilution:
Flow Cytometry: 10ul/10e6 cells
Immunohistochemistry: Frozen sections
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C before opening. DO NOT FREEZE! Stable at 4C as an undiluted liquid. Dilute only prior to immediate use. Stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. Freezing alkaline phosphatase conjugates will result in a substantial loss of enzymatic activity.
