B-lymphocyte antigen CD20 (MS4A1)-VLPs (Active), dog, recombinant

Organism: Canis lupus familiaris (Dog) (Canis familiaris). Source: Mammalian cell. Expression Region: 1-297aa. Protein Length: Full Length. Tag Info: C-terminal 10xHis-tagged (This tag can be tested only under denaturing conditions). Target Protein Sequence: MTTPRNSMSG TLPVDPMKSP TAMYPVQKII PKRMPSVVGP TQNFFMRESK TLGAVQIMNG LFHIALGSLL MIHTDVCAPI CITMWYPLWG GIMFIISGSL LAAADKNPRK SLVKGKMIMN SLSLFAAISG IIFLIMDIFN ITISHFFKME NLNLIKAPMP YVDIHNCDPA NPSEKNSLSI QYCGSIRSVF LGVFAVMLIF AFFQKLVTAG IVENEWKKLC SKPKSDVVVL LAAEEKKEQP IETTEEMVEL TEIASQPKKE EDIEIIPVQE EEGELEINFA EPPQEQESSP IENDSIP. Purity: The purity information is not available for VLPs proteins. Endotoxin: Less than 1.0 EU/ug as determined by LAL method. Biological Activity: Measured by its binding ability in a functional ELISA. Immobilized Dog CD20 at 10 µg/mL can bind Anti-CD20 recombinant antibody (CSB-RA015007MA3HU), the EC50 is 147.3-199.0 ng/mL. Form: Lyophilized powder. Buffer: Lyophilized from a 0.2 µm filtered PBS, 6% Trehalose, 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 indeionized sterile water to a concentration of 0.1-1.0 mg/mL.Aliquot for long-term storage at -80 °C. Solubilize for 60 minutes at room temperature with occasional gentle mixing. Avoid vigorous shaking or vortexing. 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: The VLPs are expressed from human 293 cells (HEK293).Mix the sample gently by repeatedly pipetting it up and down. Do not vortex.Repeated freezing and thawing is not recommended.Store the protein at -20 °C/-80 °C upon receiving it, and ensure to avoid repeated freezing and thawing, otherwise, it will affect the protein activity. The immunization strategy should be optimized (antigen dose, regimen and adjuvant). Relevance: n/a. Reference: n/a. Function: B-lymphocyte-specific membrane protein that plays a role in the regulation of cellular calcium influx necessary for the development, differentiation, and activation of B-lymphocytes. Functions as a store-operated calcium (SOC) channel component promoting calcium influx after activation by the B-cell receptor/BCR.
