MECA-32 is a 50-55 kD homodimer glycoprotein primarily expressed on most endothelial cells in the embryonic and the adult mouse tissues, except in the brain and in skeletal and cardiac muscle, where it has more restricted distribution. In skeletal and cardiac muscle, the MECA-32 antigen is confined in small arterioles and venules. But in some conditions, such as inflammation or cardiac transplantation, MECA-32 expression can be induced on some negative-cardiac endothelial cells. In the brain, its expression occurs only in the circumventricular organs and the neurohemal tissues. During embryonic development, MECA-32 antigen is expressed on the brain vasculature up to day 16 of gestation, and disappears at day 17 and after.Product Details
- Antibody Type
- Host Species
- Mouse lymph node stromal cells
- Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and 1 mM EDTA.

- 0.5 mg/ml
- Storage & Handling
- The antibody solution should be stored undiluted between 2°C and 8°C. Do not freeze.
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 (in the relevant formats) include: immunoprecipitation, Western blotting, immunocytochemistry, and immunohistochemical staining of acetone-fixed frozen sections2-5. Clone MECA-32 is not recommended for formalin-fixed paraffin sections.
- Additional Product Notes
TotalSeq™ reagents are designed to profile protein levels 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 biolegend.com/totalseq.
The TotalSeq™-A barcode sequence associated with clone MECA-32 is CGTCCTAGTCATTGG.
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
