Immunofluorescent analysis of Grasp65 in HeLa cells. The cells were fixed with 4% formaldehyde for 15 mins, permeabilized with 0.25% Triton X-100 in PBS for 10 mins, and blocked with 3% BSA in PBS for 30 mins at RT. Cells were stained with a Grasp65 rabbit polyclonal antibody (Product # PA3-910) at a dilution of 1:200 in 3% BSA in PBS for 1 hr at RT, and then incubated with Invitrogen Alexa Fluor Plus 488 goat anti-rabbit IgG secondary antibody (Product # A32723) at a dilution of 1:1000 for 1 hr at RT. Nuclei were stained with Hoechst 33342 (product # H3570). The image contains overlay of Grasp65 (green) and nuclei (blue). Images were taken on a Zeiss LSM 710 confocal microscope at 40X magnification.

Membranes were probed with a PDI monoclonal antibody (Product # MA3-019) at a dilution of 1:5000 and a p23 monoclonal antibody at a dilution of 1:1000 (Product # MA3-414) overnight at 4°C on a rocking platform, washed with TBST, and probed with an Invitrogen Alexa Fluor Plus 680 Goat anti-Mouse IgG secondary antibody (Product # A32729) at dilutions of 1:40,000 for 45 minutes. Blots were imaged on an Infrared fluorescence imaging system.
Mice were transcardially perfused with phosphate-buffered saline followed by 4% paraformaldehyde in phosphate buffer. Thirty µm serial sections were cut in a freezing microtome and transferred to phosphate-buffered saline. Free-floating sections were incubated with 1% hydrogen peroxide to quench endogenous peroxidase activity, blocked in 5% normal goat serum, then stained with a rabbit polyclonal antibody to calbindin D-28K (Chemicon) at a 1:1000 dilution. After washing, sections were incubated with Alexa Fluor® 488 goat anti-rabbit IgG antibody (Prod # A11008) at 5 µg/mL (upper panel) or HRP-goat anti-rabbit IgG antibody at 1 µg/mL, followed by Alexa Fluor® 488 tyramide (in TSA Kit #12, T20922; lower panel). Sections were washed, mounted on slides, coverslipped with ProLong® antifade reagent (in Kit P7481) and imaged under identical conditions (10X magnification, 250 millisecond exposure) using a bandpass filter set appropriate for fluorescein (FITC).
Western blot analysis of Heat Shock Protein 90 (Hsp90) and histone deacetylase 1 (HDAC1) was performed by loading 3-fold serial dilutions of A431 whole cell lysate (starting at 15ug) and 2ul of the PageRuler Prestained NIR Protein Ladder (Product # 26635) per well onto a 4-20% Tris-HCl polyacrylamide gel. Proteins were transferred to Nitrocellulose Membranes (Product # 88018) and blocked with Fluorescence Blocker for 30 min. Membranes were probed with a Hsp90 polyclonal antibody (Product # PA3-013) at a dilution of 1:5000 and an HDAC1 polyclonal antibody at a dilution of 1:5000 (Product # PA1-1110) overnight at 4°C on a rocking platform, washed with TBST, and probed with an Invitrogen Alexa Fluor Plus 680 Goat anti-Rabbit IgG secondary antibody (Product # A32734) at dilutions of 1:40,000 for 45 minutes. Blots were imaged on an Infrared fluorescence imaging system.
