B-lymphocyte antigen CD20 (Ms4a1), partial, mouse, recombinant

Organism: Mus musculus (Mouse). Source: E.coli. Expression Region: 132-291aa. Protein Length: Partial. Tag Info: N-terminal 6xHis-SUMO-tagged. Target Protein Sequence: ILNMTLSHFL KMRRLELIQT SKPYVDIYDC EPSNSSEKNS PSTQYCNSIQ SVFLGILSAM LISAFFQKLV TAGIVENEWK RMCTRSKSNV VLLSAGEKNE QTIKMKEEII ELSGVSSQPK NEEEIEIIPV QEEEEEEAEI NFPAPPQEQE SLPVENEIAP. 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: This protein may be involved in the regulation of B-cell activation and proliferation. Reference: CD20 deficiency in humans results in impaired T cell-independent antibody responses.Kuijpers T.W., Bende R.J., Baars P.A., Grummels A., Derks I.A.M., Dolman K.M., Beaumont T., Tedder T.F., van Noesel C.J.M., Eldering E., van Lier R.A.W.J.
