- Restrictions
- For Research Use only
-
- Format
- Lyophilized
- Reconstitution
- Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water.
- Buffer
- Lyophilized from 0.22μm filtered solution in PBS ( pH 7.4). Normally 5 % trehalose is added as protectant before lyophilization.
- Storage
- 4 °C,-80 °C
- Storage Comment
- Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
- Expiry Date
- 12 months

- Target
- SIRP AlphaV2
- Alternative Name
- SIRP alpha V2
- Background
- CD172a, BIT, MFR, MYD1, MYD-1, P84, PTPNS1, SHP substrate 1, SHPS1, SHPS-1, SHPS1CD172A, SIRP alpha, SIRPA, Sirp-alpha-1, SIRPalpha2, Sirp-alpha-2, Sirp-alpha-3,Signal regulatory protein α (SIRPα) is a regulatory membrane glycoprotein from SIRP family expressed mainly by myeloid cells and also by stem cells or neurons.SIRPα acts as inhibitory receptor and interacts with a broadly expressed transmembrane protein CD47 also called the "don´t eat me" signal.Cancer cells highly expressed CD47 that activate SIRP α and inhibit macrophage-mediated destruction.
- Molecular Weight
- 38 kDa. Due to glycosylation, the protein migrates to 55-65 kDa based on Tris-Bis PAGE result.
