Complement receptor type 2 (CR2), also known as complement C3d receptor, Epstein–Barr virus receptor, and CD21 (cluster of differentiation 21), is a protein that in humans is encoded by the CR2 gene.

CRISPR-Cas9 deletion of CD21 on the Jurkat T-cell line confirmed that CD21 is required for EBV infection. This study has broad implications, as we have defined a function for CD21 on mature peripheral T cells, i.e., as a receptor for EBV.

Here, we show that CD21 –/low cells represent approximately 5% of B cells in peripheral blood from adults but are barely detectable in cord blood, after excluding transitional B cells.

California's 21st congressional district (or CA-21) is a congressional district in the U.S. state of California. It is located in the San Joaquin Valley and includes parts of Fresno County and Tulare County.

Know comprehensive CD21 protein information including protein sequence, molecular weight, theoretical pI, structure, function and protein interaction.

CD21 (complement receptor 2 / CR2) is 145-kDa type I transmembrane glycoprotein. It belongs to a family of complement proteins, known as regulators of complement activation. The human CD21 gene is located at chromosome 1q32 that is tightly linked to the genes for CD3 5, CD5 5 and C4-binding protein.

CD21, also known as complement receptor 2 (CR2), is a protein expressed on the surface of B cells and follicular dendritic cells that plays a vital role in the immune response by binding to complement components and facilitating B cell activation and differentiation.

CD21 is a 145 kDa transmembrane protein that contains 15 tandem SCR/SUSHI repeats. CD21 is primarily expressed on B cells, follicular dendritic cells, and T cells. It binds the complement component fragments iC3b, C3d, and C3d,g and forms complexes with CD19 and CD35.

CD21 (EP3093) Rabbit Monoclonal Primary Antibody is intended for laboratory use in the detection of the CD21 protein in formalin-fixed, paraffin-embedded tissue stained on VENTANA BenchMark IHC/ISH instruments.

21 is the second studio album by the English singer-songwriter Adele. It was released on 24 January 2011 [4] in Europe by XL Recordings and on 22 February 2011 in North America by Columbia Records. The album was named after the age of the singer during its production.

Jul 1, 2001 · In this study, we use a recombinant protein containing three tandemly arranged copies of C3d and the Ag hen egg lysozyme, shown to be a highly effective immunogen in vivo, to evaluate the role of the CD19/CD21 complex in Ag processing in B cells.

CD21, also known as complement receptor 2 (CR2), is a protein with a molecular weight of 145-kDa that is present on mature B-cells and follicular dendritic cells. It serves as a receptor for …

Antibodies that detect CD21 can be used in several scientific applications, including Immunohistochemistry, Flow Cytometry, Western Blot, ELISA and Immunocytochemistry. These antibodies target CD21 in Human, Mouse, Rat, Bovine …

CD21, a recognized marker for B cells, plays a pivotal role in B cell activation and the formation of immunological memory. Recognizing activated products of complement 3, CD21 is instrumental in the uptake and retention of immune complexes.

CD21 is a ligand-binding component of the CD19/CD21/CD81 signal-transduction complex associated with the antigen receptor on B lymphocytes. CD21/CD35 also co-localizes with CD19 on the surface of peritoneal mast cells. Cr2null mice display impaired inflammatory and humoral immune responses in vivo.
