Vector Labs Ab03120-8.1 Anti-XCR1 [MARX10], Rat IgG2b, kappa (200 μg)
Quick Overview
The original antibody was generated by immunizing B6.XCR1-lacZ mice every 3 weeks (4 times in succession) with 30 × 10^6 CD11c-enriched cells from C57BL/6 WT mice in combination with heat-inactivated B. pertussis.

| Chimeric Use Statement: | This chimeric rat antibody was made using the variable domain sequences of the original Mouse IgG2b format for improved compatibility with existing reagents assays and techniques. |
| Specificity Statement: | This antibody binds mouse XCR1, which is a receptor for chemokines SCYC1 and SCYC2 and expressed on 80% of CD8+ the dendritic cells. It transduces a signal by increasing the intracellular calcium ions level. This antibody is also reported to cross-reacts with rat CXR1. |
| Application Notes: | This antibody was used to stain cryostat sections (12 μm) of spleens from C57BL/6 WT and B6.XCR1-lacZ mice. It was found that this antibody could stain 20% of splenic conventional dendritic cells in C57BL/6 WT mice but did not give a signal in homozygous B6.XCR1-lacZ animals, which lack the XCR1 receptor. This antibody was also used to subsets of dendritic cells that express XCR1 using flow cytometry (Bachem et al., 2012; PMID: 22826713). Digoxigenin (Dig) coupled MARX10 was injected into C57BL/6 mice for in vivo labeling of XCR1+ dendritic cells. Recombinant ovalbumin (OVA) coupled MARX10 (MARX10-OVA) was used to measure antibody levels in C57BL/6 and homozygous B6.XCR1-lacZ mice serum following injection and for an in vivo cytotoxicity assay; MARX10-OVA was found to be highly effective in inducing CD8+ T cell cytotoxicity in vivo (Hartung et al., 2015; PMID: 25520399). This antibody has been added to the Antibody Registry (RRID: AB_3668949). |
