Product Specific Information
The eBio22D1 monoclonal antibody reacts with mouse SIGNR1 (CD209b), a type II transmembrane C-type lectin identified as a mouse homologue of human DC-SIGN. SIGNR1 is highly expressed in splenic marginal zone macrophages and lymph node medullary macrophages, functioning in uptake of dextran polysaccharides and Streptococcus pneumoniae capsular polysaccharides. SIGNR1 associates with TLR4/MD2, suggesting a role in LPS recognition. SIGNR1-deficient mice show defects in complement component C3 catabolism, and SIGNR1 binds complement subcomponent C1q to form a non-conventional C3 convertase.
The eBio22D1 antibody does not cross-react with SIGNR2, SIGNR3, or SIGNR4.
Applications Reported:
- Flow cytometry
- Immunoprecipitation
- Immunohistology (frozen tissue)
- ELISA
- In vivo injection induces temporary SIGNR1 knockdown
Applications Tested:
- Flow cytometric analysis of mouse splenocytes
Recommended ≤ 0.5 µg per test (defined as staining 10⁵–10⁸ cells in 100 µL).
Optimize dilution for best performance.
Storage and Handling:
- Use in sterile environment
- 0.2 µm post-manufacturing filtered
- Purity: >90% (SDS-PAGE)
- Endotoxin: <0.001 ng/µg (LAL assay)
- Aggregation: <10% (HPLC)
Target Information
SIGNR1 is a type II transmembrane C-type lectin expressed in macrophages of spleen and lymph node, mediating uptake of polysaccharides and interacting with TLR4/MD2 in LPS recognition. SIGNR1 binds complement C1q to assemble a non-conventional C3 convertase, and its deficiency leads to defects in complement catabolism.
