Background information
Maturation of cytotoxic T lymphocytes is mediated in part by a structure on the T cell surface known as the T cell antigen receptor (TCR) complex. The pre-TCR complex consists of pre-TCR α, pre-TCR βand CD3, which together help coordinate early thymocyte development. Pre-TCR α chain is a type I transmembrane glycoprotein with an extracellular region similar to the constant domain of the immunoglobulin supergene family. Notch3 transgenic mice lacking pre-TCR α inhibits tumor development. In humans, acute lymphoblastic leukemias (ALL) in remission have lower transcript levels of Notch3, HES-1 and pre-TCR α transcripts a and b relative to proliferating ALLs. The human pre-TCR α gene is expressed in immature T cells and maps to chromosome 6p21.3.

Advisory
Avoid freeze/thaw cycles as they may denaturate the polypeptide chains of the antibody, thus reducing its reactivity, specificity and sensitivity. For antibodies that are in liquid form or reconstituted lyophilized antibodies small amounts could become entrapped on the seal or the walls of the tube. Prior to use briefly centrifuge the vial to gather all the solution on the bottom.

Description
The Anti-TCR alpha is a α- or alpha protein sometimes glycoprotein present in blood. This antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided. Antibody for research use.

About
Polyclonals can be used for Western blot, immunohistochemistry on frozen slices or parrafin fixed tissues. The advantage is that there are more epitopes available in a polyclonal antiserum to detect the proteins than in monoclonal sera.
