Desmoplakin 1/2 antibody | DP-2.15
Mouse anti Human desmoplakin 1/2 antibody, clone DP-2.15 (2722-5204) used for the detection of desmoplakin expressing human cardiomyocytes by immunofluorescence.
Image caption:
Cardiac matrix coatings increase hESC derived cardiomyocyte maturation compared to the standard gelatin substrate. hESC derived cardiomyocytes were cultured on gelatin (a and c) or cardiac matrix (b and d) and stained for Titin M8 (red), desmoplakin (green), or nuclei (blue). Cell cluster area (e), number of nuclei per cluster (f), and average desmoplakin positive area (g) were measured and compared between the two coatings. Cardiomyocytes had an increased cluster area and number of nuclei at both day 35 and 112. At day 112, the average desmoplakin immunoreactive area was significantly greater on the cardiac matrix, with localization observed at the lateral ends of the cardiomyocytes (arrows), indicating the formation of desmosomes and a more mature phenotype. **p<0.01.

Mouse anti Desmoplakin 1/2 antibody (2722-5204) used for the detection of desmoplakin expressing cells in porcine meninges by immunohistochemistry on formalin fixed, paraffin embedded tissue sections.
Image caption:
Immunohistochemical analysis of the porcine meninges. The meninges composed of the dura mater (A–G), the arachnoid mater (H–I) and the pia mater (J–M) in formalin fixed tissue. The porcine spinal cord was cryosectioned and the porcine dura mater (N–O) was stained. The tissue sections were labeled for: (A) von Willebrand factor, (B and K) fibronectin, (C and J) vimentin, (D) laminin, (E) collagen I, (F and M) collagen II, (G, H, and L) integrin 1β, (I) Desmoplakin, (N) collagen III, (O) E-cadherin. Images were captured at ×200 magnification.

Mouse anti Human desmoplakin 1/2 antibody, clone DP-2.15 (2722-5204) used to demonstrate desmoplakin expression in BeWo cells in vitro by immunofluorescence.
Image caption:
Validation of trophoblastic properties in newly derived BeWo-NG cells.
c) BeWo-NG cells can undergo syncytilialization after FSK A stimulation. Confluent cells were treated with 10 μmol/L FSK A for 24 h. Cells were fixed in cold acetone/methanol and permeabilization using 0.1% saponin in 1% BSA. Cells were then stained with desmoplakin specific primary antibody and Alexa 488 conjugated secondary antibody before visualization using fluorescent microscopy. The nuclei of cells were counterstained with DAPI nuclear dye. Red lines are drawn around the boundary of Syncytialized cells. Micrographs were taken under 200X magnification
