Mouse anti Pig SLA Class I antibody, clone JM1E3 (**MCA2261GA**) used for the evaluation of SLA Class I expression on bone marrow derived mesenchymal stem cells by flow cytometry.
**Image caption:**
Effect of pericardial fluid on pBM-MSCs phenotype. The phenotypic analysis was performed by multicolor flow cytometry. The cells were in vitro cultured for 7 days in the presence of Fetal Bovine Serum and in the presence of pericardial fluid at 25%, 50%, 75% and 100%. Representative histograms of four different experiments are shown (A). The expression level of Stem Cell Markers (CD29, CD31, CD44, CD90, CD105) and Swine Leukocyte Antigen Class-I and Class-II (SLA-I and SLA-II) is represented as Normalized Mean Relative Fluorescence Intensity which is calculated by dividing the Mean Fluorescent Intensity (MFI) by its isotype control. Graphic representation of mean±SD for each marker is also provided (n = 4) (B). No significant differences were found between groups when ANOVA test was performed.

Mouse anti Pig SLA Class I antibody, clone JM1E3 (**MCA2261GA**) used for the evaluation of SLA Class I expression in cells over-expressing β2-microglobulin by immunofluorescence.
**Image caption:**
Immunohistochemical analysis of the β2M and SLA class I expression in cells over-expressing β2M. The names of the transfected constructs are shown on top: pCMV-HA-B2M for the expression of HA-tagged β2M, pCMV-HA for the HA tag without β2M, and pEGFP-N1 for EGFP expression. The primary antibodies used for the analysis are shown on the left. A and B. Cells were stained with the HA tag-specific antibody. The cell nuclei were visualized using 4′,6-diamidino-2-phenylindole (DAPI; blue). C. pEGFP (green) plasmid was used to evaluate the transfection efficiency. D, E, and F. SLA class I heavy chains were stained with pan SLA class I-specific antibodies. The signals of primary antibodies were detected by Alexa 568-conjugated secondary antibody (red) in all cases.

Mouse anti Pig SLA Class I antibody, clone JM1E3 recognizes a monomorphic epitope expressed by porcine MHC class I molecules (SLA - 1). SLA - 1 is expressed by all nucleated porcine cells, but not on erythrocytes. This antibody has also been shown to cross-react with human MHC Class I, including HLA-E. (Galiani et al. 2002)

The major histocompatibility complex (MHC) is a cluster of genes that are important in the immune response to infections. In pigs, this is referred to as the swine leukocyte antigen (SLA) region.
Mouse anti pig SLA class I, clone JM1E3 has been reported to block the interaction of MHC Class I antigens with inhibitory NK cell receptors (Galiani et al. 2002).
