TotalSeq™ anti-mouse Hashtag reagent is a mixture of two monoclonal antibodies conjugated to the same oligonucleotide. The antibodies are specific against mouse CD45 and MHC class I (of a, b,  d, j, k, s, and u haplotypes) and can be used to label hematopoietic and non-hematopoietic cells in most commonly used mouse strains for multiplex single cell sequencing analysis. The conjugated antibodies are pre-mixed to be used following an optimized protocol similar to the CITE-seq workflow.

CD45 is a 180-240 kD glycoprotein also known as the leukocyte common antigen (LCA), T200, or Ly-5. It is a member of the protein tyrosine phosphatase (PTP) family, expressed on all hematopoietic cells except mature erythrocytes and platelets. CD45 plays a key role in TCR and BCR signal transduction.

MHC class I is involved in antigen presentation to T cells expressing CD3/TCR and CD8 proteins. The M1/42 antibody reacts with the H-2 MHC class I alloantigens expressed on nucleated cells from mice of the a, b, d, j, k, s, and u haplotypes (Stallcup, KC et al, 1981).

Importantly, some cell lines or experimental models may lack or express very low levels of either or both CD45 and MHC I molecules. We recommend a pilot experiment before single cell proteogenomics to confirm expression of these molecules in your experimental system. Different mouse strains express different MHC I haplotypes. Please refer to the supplemental table for detailed information about the haplotype of your experimental model. The supplemental table and summary below are not exhaustive and provide just a summary of common laboratory mouse strains recognized by TotalSeq™ anti-mouse Hashtags.

PG - Quality tested

Recommended Usage

Each lot of this reagent 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 0.1 to 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 (0.1 - 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. It is also recommended that users test the reactivity of the reagents to their target cells of interest before actual studies.

Additional Product Notes

TotalSeq™ Hashtag reagents can be used for multiplexing different samples; optimization of microfluidics instruments to load a high number of cells, and discriminate droplets containing  more than one cell; performing TotalSeq™ antibody titrations, etc.  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 barcode sequence associated with anti-mouse Hashtag 14 is CTTTCGCCAACTCTG.

The flanking sequences are GTGACTGGAGTTCAGACGTGTGCTCTTCCGATCT, and the poly A tail, BAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA*A*A, where 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 GTGACTGGAGTTCAGACGTGTGCTCTTCCGATCT [CTTTCGCCAACTCTG]BAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA*A*A.
