Alexa fluor 488 green fluorescence conjugated goat anti mouse

Cells cultured on CTRL and TEST tested surfaces were fixed for 10 min at room temperature (RT) with 4% paraformaldehyde in 0.1 M sodium phosphate buffer (PBS), pH 7.4 [31 (link)]. Successively washing in PBS, cultures were prepared for immunofluorescence labeling. The hPDLSCs cultured on the titanium surfaces were permeabilized with 0.1% Triton X-100 in PBS, followed by blocking with 5% skimmed milk in PBS. Primary monoclonal antibodies to anti human VEGF (Santa Cruz Biotechnology, Santa Cruz, CA; USA), VEGF-R (Santa Cruz Biotechnology), and RUNX2 (Santa Cruz Biotechnology) were utilized, followed by Alexa Fluor 488 green fluorescence conjugated goat anti-mouse as secondary antibodies (Molecular Probes, Invitrogen, Eugene, OR, USA). Successively, samples were incubated with Alexa Fluor 594 phalloidin red fluorescence conjugate (Molecular Probe), as an actin cytoskeleton marker. Nuclei were dyed with TOPRO (Molecular Probe). Samples were put down on glass slides and mounted with Prolong antifade (Molecular Probes) [32 (link)]. Dyeing of samples was seen utilizing a Zeiss (Jena, Germany) LSM510 META confocal system, connected to an inverted Zeiss Axiovert 200 microscope supplied with a Plan Neofluar oil-immersion objective (40×/1.3 NA). The pictures were taken utilizing an argon laser beam with excitation lines at 488 nm.
