Description

This antibody is highly specific and optimized for use in Immunohistochemistry.

It has been validated on TMAs covering 76 normal tissues and numerous cancer tissues.

The antibody concentration is optimized for dilution within dilution range using commercially available antibody diluent for immunohistochemistry.

Positive Control
Postive control:Tonsil: A strong membranous CD45RA immunostaining should be seen in the majority of lymphocytes..

Negative Control
Negitve control:Tonsil: CD45RA immunostaining should be absent in epithelial cells.

Storage
Antibody can be stored at 4degC. For extended storage, aliquot and store at -20degC. Avoid repeated freeze-thaw cycles.

Background: CD45RA

The CD45 molecule is comprised of different glycoproteins ranging from 180-240 kD. Expression of CD45 is found on all hemopoietic cells. Detection of the different isoforms can distinguish between different cell forms i.e. naive T cells and memory T cells. CD45RA is an isoform of the CD45 complex and has restricted expression between different subtypes of lymphoid cells. The functional activity of each CD45 isotype also varies.
