Granulocyte-macrophage colony-stimulating factor receptor subunit alpha (CSF2RA), partial (Active),

Organism: Homo sapiens (Human). Source: Mammalian cell. Expression Region: 23-320aa. Protein Length: Partial. Tag Info: C-terminal 6xHis-tagged. Target Protein Sequence: EKSDLRTVAP ASSLNVRFDS RTMNLSWDCQ ENTTFSKCFL TDKKNRVVEP RLSNNECSCT FREICLHEGV TFEVHVNTSQ RGFQQKLLYP NSGREGTAAQ NFSCFIYNAD LMNCTWARGP TAPRDVQYFL YIRNSKRRRE IRCPYYIQDS GTHVGCHLDN LSGLTSRNYF LVNGTSREIG IQFFDSLLDT KKIERFNPPS NVTVRCNTTH CLVRWKQPRT YQKLSYLDFQ YQLDVHRKNT QPGTENLLIN VSGDLENRYN FPSSEPRAKH SVKIRAADVR ILNWSSWSEA IEFGSDDG. Purity: Greater than 95% as determined by SDS-PAGE. Endotoxin: Less than 1.0 EU/µg as determined by LAL method. Biological Activity: The ED50 as determined by its ability to inhibit GM-CSF-dependent proliferation of TF-1 human erythroleukemic cells is 0.5-2 µg/ml. Form: Lyophilized powder. Buffer: Lyophilized from a 0.2 µm filtered 20 mM PB, 150 mM NaCl, pH 7.4. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Granulocyte-Macrophage Colony-Stimulating Factor Receptor Subunit alpha (CSF2RA) is a single-pass type I membrane protein which belongs to the type I cytokine receptor family of Type 5 subfamily. The CSF2RA gene is found in the pseudoautosomal region (PAR) of the X and Y chromosomes with some of the isoforms being membrane-bound and others being soluble. CSF2RA is a low affinity receptor for granulocyte-macrophage colony-stimulating factor. CSF2RA transduces a signal that results in the proliferation, differentiation, and functional activation of hematopoietic cells. Defects in CSF2RA are the cause of pulmonary surfactant metabolism dysfunction type 4 (SMDP4). Reference: n/a. Function: Low affinity receptor for granulocyte-macrophage colony-stimulating factor. Transduces a signal that results in the proliferation, differentiation, and functional activation of hematopoietic cells.
