Related Product Information for CD19 recombinant protein
CD19, also known as B-lymphocyte antigen CD19 isoform 1, is a member of the Ig superfamily expressed on the surface of all B-lymphoid cells with the exception of terminally differentiated plasma cells. It has been implicated as a signal-transducing receptor in the control of proliferation and differentiation. It acts as an adaptor protein to recruit cytoplasmic signaling proteins to the membrane and it works within the CD19/CD21 complex to decrease the threshold for B cell receptor signaling pathways. Due to its presence on all B cells, it is a biomarker for B lymphocyte development, lymphoma identification and can be utilized as a target for leukemia immunotherapies. Recombinant human CD19, fused to hIgG-His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.

NCBI Description

Lymphocytes proliferate and differentiate in response to various concentrations of different antigens. The ability of the B cell to respond in a specific, yet sensitive manner to the various antigens is achieved with the use of low-affinity antigen receptors. This gene encodes a cell surface molecule which assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation. [provided by RefSeq, Jul 2008]

Uniprot Description

CD19: a cell surface molecule which assembles with the antigen receptor of B lymphocytes. A critical signal transduction molecule that regulates B lymphocyte development, activation, and differentiation. Ligation increases intracellular calcium levels and decreases the threshold for antigen receptor signaling. Germinal center formation is significantly reduced in CD19-deficient mice.

Product Notes

The CD19 cd19 (Catalog #AAA201082) is a Recombinant Protein produced from Baculovirus and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is 21-291aa. AAA Biotech's CD19 can be used in a range of immunoassay formats including, but not limited to, SDS-PAGE. Researchers should empirically determine the suitability of the CD19 cd19 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. The amino acid sequence is listed below: EEPLVVKVEE GDNAVLQCLK GTSDGPTQQL TWSRESPLKP FLKLSLGLPG LGIHMRPLAI WLFIFNVSQQ MGGFYLCQPG PPSEKAWQPG WTVNVEGSGE LFRWNVSDLG GLGCGLKNRS SEGPSSPSGK LMSPKLYVWA KDRPEIWEGE PPCLPPRDSL NQSLSQDLTM APGSTLWLSC GVPPDSVSRG PLSWTHVHPK GPKSLLSLEL KDDRPARDMW VMETGLLLPR ATAQDAGKYY CHRGNLTMSF HLEITARPVL WHWLLRTGGW KLEPKSCDKT HTCPPCPAPE LLGGPSVFLF PPKPKDTLMI SRTPEVTCVV VDVSHEDPEV KFNWYVDGVE VHNAKTKPRE EQYNSTYRVV SVLTVLHQDW LNGKEYKCKV SNKALPAPIE KTISKAKGQP REPQVYTLPP SRDELTKNQV SLTCLVKGFY PSDIAVEWES NGQPENNYKT TPPVLDSDGS FFLYSKLTVD KSRWQQGNVF SCSVMHEALH NHYTQKSLSL SPGKHHHHHH. It is sometimes possible for the material contained within the vial of "CD19, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
