Mouse anti-Chicken CD45 Monoclonal Antibody | anti-PTPRC antibody
Mouse Anti-Chicken CD45-UNLB
Chicken CD45 is a transmembrane glycoprotein expressed on all leukocytes. B lineage cells in the bursa of Fabricius express the 215 kDa isoform while T lineage cells bear the 190 kDa variant. These high molecular weight molecules have intrinsic phosphotyrosine phosphatase activity characteristic of mammalian CD45.1 Levels of CD45 expression detected by MAb LT40 in the avian thymus are heterogeneous with approximately 90% of thymocytes expressing fourfold higher levels of surface CD45 (CD45hi) than do the remaining 10% (CD45lo) of thymocytes. The CD45lo population contains exclusively thymocytes with the CD3-CD4-CD8lo phenotype characteristic of the immediate precursors to the CD3- CD4+CD8+ thymic population which are CD45hi. This shift from low to high levels of surface CD45 expression is concomitant with the transition from CD4-CD8lo to CD4+CD8+ and before the expression of CD3. The ability of MAb LT40 to discriminate this CD45lo subpopulation provides a suitable marker for the CD3-CD4-CD8lo immediate precursors to the CD3-CD4+CD8+ thymocytes.1

NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP contains an extracellular domain, a single transmembrane segment and two tandem intracytoplasmic catalytic domains, and thus belongs to receptor type PTP. This gene is specifically expressed in hematopoietic cells. This PTP has been shown to be an essential regulator of T- and B-cell antigen receptor signaling. It functions through either direct interaction with components of the antigen receptor complexes, or by activating various Src family kinases required for the antigen receptor signaling. This PTP also suppresses JAK kinases, and thus functions as a regulator of cytokine receptor signaling. Four alternatively spliced transcripts variants of this gene, which encode distinct isoforms, have been reported. [provided by RefSeq]
Uniprot Description
Function: Protein tyrosine-protein phosphatase required for T-cell activation through the antigen receptor. Acts as a positive regulator of T-cell coactivation upon binding to DPP4. The first PTPase domain has enzymatic activity, while the second one seems to affect the substrate specificity of the first one. Upon T-cell activation, recruits and dephosphorylates SKAP1 and FYN. Ref.6 Ref.8
Catalytic activity: Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.
Subunit structure: Binds GANAB and PRKCSH
By similarity. Interacts with SKAP1. Interacts with DPP4; the interaction is enhanced in a interleukin-12-dependent manner in activated lymphocytes. Ref.8 Ref.9
Subcellular location: Membrane; Single-pass type I membrane protein. Membrane raft. Note: Colocalized with DPP4 in membrane rafts. Ref.9
Domain: The first PTPase domain interacts with SKAP1.
Post-translational modification: Heavily N- and O-glycosylated. Ref.12 Ref.13
Involvement in disease: Defects in PTPRC are a cause of severe combined immunodeficiency autosomal recessive T-cell-negative/B-cell-positive/NK-cell-positive (T-B+NK+ SCID) [
MIM:608971]. A form of severe combined immunodeficiency (SCID), a genetically and clinically heterogeneous group of rare congenital disorders characterized by impairment of both humoral and cell-mediated immunity, leukopenia, and low or absent antibody levels. Patients present in infancy recurrent, persistent infections by opportunistic organisms. The common characteristic of all types of SCID is absence of T-cell-mediated cellular immunity due to a defect in T-cell development. Ref.18Genetic variations in PTPRC are involved in multiple sclerosis susceptibility (MS) [
MIM:126200]. MS is a neurodegenerative disorder characterized by the gradual accumulation of focal plaques of demyelination particularly in the periventricular areas of the brain. Peripheral nerves are not affected. Onset usually in third or fourth decade with intermittent progression over an extended period. The cause is still uncertain. Ref.17
Sequence similarities: Belongs to the protein-tyrosine phosphatase family. Receptor class 1/6 subfamily.Contains 2 fibronectin type-III domains.Contains 2 tyrosine-protein phosphatase domains.

Product Notes
The PTPRC ptprc (Catalog #AAA673896) is an Antibody produced from Mouse and is intended for research purposes only. The product is available for immediate purchase. The Mouse Anti-Chicken CD45-UNLB reacts with Chicken and may cross-react with other species as described in the data sheet. AAA Biotech's CD45 can be used in a range of immunoassay formats including, but not limited to, Flow Cytometry; Immunoprecipitation. Research Application(s): Studies of avian T cell development 1. Researchers should empirically determine the suitability of the PTPRC ptprc for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "CD45, Monoclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
