重组Anti-Calponin 1抗体[EP798Y] (ab46794)

Immunocytochemistry/ Immunofluorescence analysis of C2C12 (Mouse myoblasts myoblast) cells labeling Calponin 1 with purified ab46794 at 1/500 dilution. Cells were fixed in 4% paraformaldehyde and permeabilized with 0.1% Triton X-100. Cells were counterstained with ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor^® 594) 1/200 (2.5 μg/ml). ab150077 Goat anti rabbit IgG(Alexa Fluor^® 488) was used as the secondary antibody at 1:1000 dilution. DAPI nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.

Blocking and diluting buffer: 5% NFDM/TBST.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human lung carcinoma tissue sections labeling Calponin 1 with purified ab46794 at a 1:1000 dilution. Heat mediated antigen retrieval was performed using ab93684 (Tris/EDTA buffer, pH 9.0). Tissue was counterstained with hematoxylin. ImmunoHistoProbe one step HRP Polymer (ready to use) secondary antibody was used.

PBS instead of the primary antibody was used as the negative control (inset).

Ab46794 was used to stain Calponin 1 in Neonatal piglets injected with Dox (Failing LV myocardium) and PBS (Non-Failing LV myocardium). At the protein level a more than twofold increase in Calponin 1 was observed in Dox-injected animals compared to controls (PBS).

Paraformadehyde-fixed, 0.25% Triton X-100 permeabilized mouse thoracic aortic smooth muscle cells labeling Calponin 1 using ab46794 at 1/100 dilution in ICC/IF, followed by a Goat Anti-Rabbit IgG H&L (Alexa Fluor 488) (ab150077) at 1/400 dilution.

1.5% BSA used used as blocking agent for 30 minutes at 25°C. Incubated with primary antibody for 24 hours at 4°C.

VSMCs were seeded to 35-mm plates in a low density avoiding overlapping of cells. After fixation, VSMCs were treated with 0.25% Triton X-100 for 20 minutes.

Unpurified ab46794 staining Calponin 1 in porcine aortic smooth muscle cells by Immunocytochemistry/ Immunofluorescence.

The cells were paraformaldehyde fixed, permeabilized in 0.1% Triton X-100. Samples were then incubated with primary antibody at 1/50 for 1 hour at 25°C. The secondary antibody used was ab6717 Goat polyclonal to Rabbit IgG - H&L (FITC) (green) used at a 1/400 dilution.

Representative photomicrograph of mouse UT-myo cells (Left panel) and murine uterine myometrium (Right panel) stained with smooth muscle cell markers, alpha-SMA (red) and ab46794 (green) and DAPI (blue). UT-myo cells and whole-mount uterine tissue were collected from day 19 of mouse pregnancy. The placenta and embryo were removed from whole-mount tissue sections.

ICC/IF image of unpurified ab46794 stained HeLa (Human epithelial cell line from cervix adenocarcinoma) cells.

Cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilize the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab46794, 5µg/ml) overnight at +4°C. The secondary antibody (green) was DyLight^® 488 goat anti-rabbit IgG - H&L, pre-adsorbed (ab96899) used at a 1/250 dilution for 1h. Alexa Fluor^® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
