C5L2 (C5a receptor-like 2) is a seven-transmembrane orphan receptor, also known as GPR77, which shares significant homology to C5a receptor (CD88), but it is a decoy receptor without G-protein coupling. C5L2 is co-expressed with C5aR on many kinds of cells, such as neutrophils, immature dendritic cells, mast cells, macrophages, and astrocytes. C5L2 binds C5a with similar high affinity as C5aR and relatively higher affinity for C5a-des-Arg than with C5aR.

PG - Quality tested

Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis and the oligomer sequence is confirmed by sequencing. For Proteogenomics TotalSeq™-A analysis, the suggested use of this reagent is ≤ 1.0 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

To maximize performance, centrifuge the antibody dilution (1.0 µg of antibody in 100 µl of staining buffer for every 1 million cells) before adding to the cells at 14,000xg at 2 - 8°C for 10 minutes. Carefully pipette out the liquid avoiding the bottom of the tube and add to the cell suspension.

Application Notes

Additional reported applications include: Western blotting1,3 and blocking2,3. The LEAF™ or Ultra-LEAF™ purified antibody is recommended for functional assays (contact our custom solutions team).

Clone 1D9-M12 is known to block C5a binding to C5L2, but does not react with C5a receptor. It has been reported that this clone is not effective in immunohistochemistry of formalin-fixed paraffin-embedded sections1.

Additional Product Notes

TotalSeq™ reagents are designed to profile protein expression at a single cell level following an optimized protocol similar to the CITE-seq workflow. A compatible single cell device (e.g. 10x Genomics Chromium System and Reagents) and sequencer (e.g. Illumina analyzers) are required. Please contact technical support for more information, or visit

The TotalSeq™-A barcode sequence associated with clone 1D9-M12  is ACAATTTGTCTGCGA.

The flanking sequences are CCTTGGCACCCGAGAATTCCA, and the capture sequence, BAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA*A*A, B represents either C, G, or T, and * indicates a phosphorothioated bond, to prevent nuclease degradation.

The full oligomer sequence for this product, with the specific barcode in brackets is CCTTGGCACCCGAGAATTCCA [ACAATTTGTCTGCGA]BAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA*A*A.
