Isotype | Engineer antibody |
Application | WB, IHC |
Species Reactivity | Human |
Basic Information | |
Specificity | This antibody recognises CD21L which is a long isoform of CD21 (CR2) (with an additional exon 10a). It is strongly expressed on dendritic reticulum cells and serves as a receptor for the complement elements (and is also bound by EBV). |
Alternative Name | Complement receptor type 2; CR2; Complement C3d receptor; Epstein- Barr virus receptor; EBV receptor; CD21 |
UniProt | P20023 |
Immunogen | This antibody was raised by immunising BALB/c mice with C3 receptor-coated erythrocytes. |
Application Notes | CD21L is strongly expressed in reticulum dendritic cells and R4/23 might be used for the identification of these cells. For instance, Schriever et al. (1989) used this antibody (among others) in an attempt to differentiate follicular dendritic cells from lymphoid dendritic cells. This antibody can be also utilised in the characterisation of certain cancers; for example, one group used it in an immunohistochemical analysis of frozen samples of tumour cells from diffuse large B‐cell lymphoma (Ogawa et al., 2004). |
