Thy-1 cell surface antigen Protein Datasheet

THY1 Protein Product Information

• Synonym: THY1, Thy-1
• Protein Construction: A DNA sequence encoding the rat THY1 (P01830)(Met1-Lys129) was expressed with a polyhistidine tag at the C-terminus.
• Source: Rat
• Expression Host: Human Cells

THY1 Protein QC Testing

• Purity: > 95 % as determined by SDS-PAGE
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Stability: Samples are stable for up to twelve months from date of receipt at -70℃
• Predicted N terminal: Gln 20
• Molecular Mass: The recombinant rat THY1 comprises 121 amino acids and predicts a molecular mass of 14.1 kDa. The apparent molecular mass of the recombinant protein is approximately 27-29 kDa in SDS-PAGE under reducing conditions due to glycosylation.
• Formulation: Lyophilized from sterile PBS, pH7.4.
  1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
  2. Please contact us for any concerns or special requirements.
• SDS-PAGE: THY1 protein

THY1 Protein Usage Guide

• Storage: Store it under sterile conditions at -70℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

THY1 Protein Description

Thy-1 membrane glycoprotein, also known as Thy-1 antigen, CD90 and THY1, is a cell membrane protein which contains 1 Ig-like V-type (immunoglobulin-like) domain. THY1 / CD90, a member of the immunoglobulin superfamily of adhesion molecules with constitutive expression on fibroblast cells. THY1 / CD90 is a cell surface glycoprotein originally identified on mouse thymocytes. It has been identified on a variety of stem cells and at varying levels in non-lymphoid tissues such as on fibroblasts, brain cells, and activated endothelial cells. THY1 / CD90 is a membrane glycoprotein expressed in thymus, retinal ganglionic cells, and several types of stem cells. It was observed that THY1 / CD90 cell surface expression decreased significantly during the course of infection. In adult rats, expression of THY1 / CD90 on the B cell lineage is confined to immature B cells. The expression of THY1 / CD90 on neonatal MZ-B cells may have implications for their responsiveness to polysaccharide (T cell-independent type 2) antigens. THY1 / CD90 is modulated following infection with Human cytomegalovirus (HCMV). Neuroblastoma (NBL) is the most common solid tumor in children. THY1 / CD90 seemed to be a marker with a specific prognostic value in NBL patients. THY1 / CD90 may also play a role in cell-cell or cell-ligand interactions during synaptogenesis and other events in the brain.
