Fc receptor-like protein 4 (FCRL4), partial, human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 20-387aa. Protein Length: Extracellular Domain. Tag Info: N-terminal 6xHis-SUMO-tagged. Target Protein Sequence: AHKPVISVHP PWTTFFKGER VTLTCNGFQF YATEKTTWYH RHYWGEKLTL TPGNTLEVRE SGLYRCQARG SPRSNPVRLL FSSDSLILQA PYSVFEGDTL VLRCHRRRKE KLTAVKYTWN GNILSISNKS WDLLIPQASS NNNGNYRCIG YGDENDVFRS NFKIIKIQEL FPHPELKATD SQPTEGNSVN LSCETQLPPE RSDTPLHFNF FRDGEVILSD WSTYPELQLP TVWRENSGSY WCGAETVRGN IHKHSPSLQI HVQRIPVSGV LLETQPSGGQ AVEGEMLVLV CSVAEGTGDT TFSWHREDMQ ESLGRKTQRS LRAELELPAI RQSHAGGYYC TADNSYGPVQ SMVLNVTVRE TPGNRDGL. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. 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: May function as an inhibitor of the B-cell receptor signaling. May function in the B-cell-mediated immune response.
