Provider: Invitrogen Antibodies
Product name: CD146 Monoclonal Antibody (P1H12), PE, eBioscience™
Antibody type: Monoclonal
Antigen: Other
Description: Description: The monoclonal antibody P1H12 recognizes CD146 also known as MUC18, s-endo, Endo-CAM and Mel-CAM, which is a member of the Ig superfamily of proteins. The expression of CD146 is found on endothelial cells, bone marrow fibroblasts and some tumors (especially melanoma). Recently mesenchymal stromal cells and endometrial stromal cells have also been shown to express CD146. The presence of CD146 on circulating blood cells have been confined to a subset of T cells rather than circulating endothelial cells, as expression of other endothelial markers (CD31 and CD51/61) is negative. Expression can be found on activated lymphocytes. The protein is heavily glycosylated with more than 50% of the mass from carbohydrates. The antibody P1H12 has been reported to crossreact to mouse, rabbit, canine, but not rat. Applications Reported: This P1H12 antibody has been reported for use in flow cytometric analysis. Applications Tested: This P1H12 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.125 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser. Filtration: 0.2 µm post-manufacturing filtered.

Experimental details: Fig. 4 IGF-1-dependent induction of cancer stem cell markers CD20, CD133, and CD271 (NGFR) on melanoma cells. a Melanoma cells (WM3749) co-cultured with TAB cells (days 3 and 9) show high expression of CD20 ( middle and right panels ) compared with the control culture ( left panel ) as determined by FACS analysis. Melanoma cells were co-stained with anti-CD146 (MCAM, PE-conjugated) and anti-CD20 (FITC-conjugated) antibodies to distinguish them from B cells, which are CD146-negative;percentages indicate co-expression of both markers on the malignant cells. b Melanoma cells (WM3749) co-cultured with TAB cells (day 6) show high expression of CD20, CD133 and CD271 ( left panel ) compared with minimal or low expression of those markers when tumor cells are co-cultured with NB cells ( right panel ). Co-culture of melanoma cells with TAB cells did not modulate the expression of CD144 (vascular-endothelial cadherin marker) that are normally expressed by aggressive melanomas (data not shown). Induction of CD20, CD133, and CD271 was blocked when anti-IGF-1 neutralizing antibody (10 mug/ml) was used in the co-culture ( middle panel ). Anti-IL-1, anti-PDGF or anti-VEGF antibodies had no effect on CD marker expression (data not shown). Percentages indicate co-expression of CD20, CD133, or CD271on CD146 + melanoma cells. Results are representative of two independent experiments. c Melanoma cells(WM3749, WM989 and 451Lu) cultured in the presence of recombinant IGF-1 (25 ng/ml) for 5 days sh

Experimental details: Figure 1 Characterization of isolated endothelial progenitor cells. Flow cytometric analysis of surface markers of EPCs using FITC-conjugated anti-CD146, PE-conjugated anti-CD34 and PE-Cy5-conjugated anti-CD45 monoclonal antibodies demonstrated that 78% (A) and 80% (B) of the cells were triple positive for the markers. FLI, FL2 and FL3 represent CD146, KDR and CD45 expressive cells, respectively. The percentage of expressing cells was calculated using the cell quest program.

FN1-KO cells were compared with copGFP in cell increase (A) , percentage of cells in the S and G 2 phases (B) , and surface markers [SSEA4 (C) , CD73 (D) , CD90 (E) , CD105 (F) , and CD146 (G) ] by flow cytometry; stemness genes ( NANOG, SOX2, KLF4, BMI1, MYC, NOV, POU5F1 , and NES ) (H) , senescent genes ( CDKN1A, CDKN2A , and TP53 ) (I) , and the mesenchymal condensation gene ( CDH2 ) (J) by qPCR. GAPDH was used as an endogenous control. Data are shown as bar charts. * indicates a significant difference compared to the corresponding copGFP group ( P < 0.05).
