Applications
 
WB: not recommended
IP: not tested yet
ICC: not tested yet
IHC: not tested yet
IHC-P: 1 : 100 gallery  

Western blot (WB); separation of proteins by PAGE and subsequent transfer to a membrane. Detection of target molecules is carried out with antibodies. Some antibodies require special sample preparation steps. For details, please refer to the “Remarks” section.

Immunoprecipitation (IP); Immunoisolation or pulldown of a target molecule using an antibody. For details and product specific hints, please refer to the ”Remarks” section.

Immunocytochemistry (ICC) on 4% PFA fixed cells. Immunoreactivity is usually revealed by fluorescence. Some antibodies require special fixation methods. For details, please refer to the “Remarks” section.

Immunohistochemistry (IHC) on 4% PFA perfusion fixed tissue with 24h PFA post fixation. Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate. Some antibodies require special fixation methods or antigen retrieval steps. For details, please refer to the ”Remarks” section.

Immunohistochemistry (IHC-P) of formalin fixed, paraffin embedded (FFPE) tissue (some antibodies require special antigen retrieval steps, please refer to the ”Remarks” section). Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate.

Background

CD45, also designated as Leukocyte Common Antigen (LCA) or protein tyrosine phosphatase receptor type C (PTPRC), is a type I transmembrane protein expressed on all nucleated cells of the hematopoietic system, except mature erythrocytes and platelets (1). Several isoforms of CD45 have been identified which are generated by differential splicing of exons 4, 5, and 6, thereby generating the CD45RA, RB and RC isoforms, respectively (2). Expression of the isoforms differs according to cell type and functional status. The CD45RABC (B220) long isoform is almost exclusively expressed on B cells (3). Naïve human T cells express the high molecular weight isoform CD45RA. Activation of T cells and differentiation to memory T cells is accompanied by exon exclusion for production of the short isoform CD45RO (3). CD45 has been shown to be an essential regulator of T- and B-cell antigen receptor signaling. Thus, CD45-deficient humans and mice develop a severe-combined immunodeficiency (SCID) phenotype (4). In macrophages, CD45 plays a central role in their adhesion, morphology and motility (5).
