Geprüfte Anwendungen

• Erfolgreiche Detektion in WB: Raji-Zellen
• Erfolgreiche Detektion in IHC: humanes Tonsillitisgewebe; Hinweis: Antigendemaskierung mit TE-Puffer pH 9,0 empfohlen. (*) Wahlweise kann die Antigendemaskierung auch mit Citratpuffer pH 6,0 erfolgen.

Empfohlene Verdünnung

• Western Blot (WB): WB : 1:500-1:1000
• Immunhistochemie (IHC): IHC : 1:20-1:200

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Hintergrundinformationen

CD21, also known as complement receptor type 2 (CR2), complement C3d receptor, and Epstein-Barr virus receptor, is a transmembrane protein that contains a small cytoplasmic domain, a transmembrane region and an extracellular domain consisting of 15 tandem short consensus repeat sequences (PMID: 6230668; 2551147). It is expressed on B cells, follicular dendritic cells, thymocytes and a subset of peripheral T cells (PMID: 26119182). CD21 binds complement fragments C3d, C3dg and iC3b and acts as a receptor for the Epstein-Barr virus (PMID: 7753047). On B cells, together with CD19 and CD81, CD21 forms a complex that functions as a co-receptor to the BCR (PMID: 7542009). It is involved in B cells activation and functions.
