Alexa Fluor® 647 Mouse anti-Hsp60
Alexa Fluor® 647 Mouse anti-Hsp60

Immunofluorescent staining of human cell lines.  HeLa cells (ATCC CCL-2) were cultured, fixed, permeabilized with cold methanol, stained with Alexa Fluor® 647 Mouse anti-Hsp60 (pseudo-colored green), and counter-stained with Hoechst 33342 (pseudo-colored blue) according to the Recommended Assay Procedure.  The images were captured on a BD Pathway™ 855 Bioimager System with 20x (left panel) and 40X (right panel) objectives and merged using BD Attovision™ software.  This antibody also stains A549 (ATCC CCL-185) and U-2 OS (ATCC HTB-96) cells.  Triton X-100 is not recommended as a permeabilization agent with this antibody conjugate.

Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

Recommended Assay Procedures

1.        Seed the cells in appropriate culture medium at ~10,000 cells per well in a BD Falcon™ 96-well Imaging Plate (Cat. No. 353219), and

        culture overnight.

2.        Remove the culture medium from the wells, and fix the cells by adding 100 µl of fresh 3.7% Formaldehyde in PBS or BD Cytofix™ fixation buffer (Cat. No. 554655) to each well and incubating for 10 minutes at room temperature (RT).

3.        Remove the fixative from the wells, and permeabilize the cells by adding 100 µl of -20°C 90% methanol or -20°C BD™ Phosflow Perm Buffer III (Cat. No. 558050) to each well and incubating for 5 minutes at RT.

4.        Remove the permeabilizer, and wash the wells twice with 100 μl of 1× PBS.

5.        Remove the PBS, and block the cells by adding 100 µl of blocking buffer (3% FBS in 1× PBS) or BD Pharmingen™ Stain Buffer (FBS) (Cat. No. 554656) to each well and incubating for 30 minutes at RT.

6.        Remove the blocking buffer, dilute the antibody conjugate 1:10 in blocking buffer or Stain Buffer (FBS), and stain the cells by adding 50 µl of the diluted antibody conjugate to each well and incubating for 1 hour at RT.

7.        Remove the diluted antibody conjugate, and wash the wells three times with 100 μl of 1× PBS.

8.        Remove the PBS, and counter-stain the nuclei by adding 100 μl of a 2 μg/ml solution of Hoechst 33342 (eg, Sigma-Aldrich Cat. No. B2261) in 1× PBS to each well at least 15 minutes before imaging.

9.        View and analyze the cells on an appropriate imaging instrument.  Recommended filters for the BD Pathway™ instruments are:

Instrument                        Excitation        Emission        Dichroic

BD Pathway 855                620/60                700/75                660 LP

BD Pathway 435                628/40                690/40                FF660

24/HSP60

Heat shock proteins (Hsp) are a set of highly conserved proteins that include constitutively expressed (Hsp60, Hsp70, and Hsp90) and stress-induced (Hsp27 and Hsp72) proteins. Hsp60 is localized to the mitochondria, where it promotes mitochondrial protein folding and facilitates proteolytic degradation of misfolded or denatured proteins. It binds Hsp10, which regulates the substrate binding and ATPase activity of Hsp60. In HeLa and Jurkat mitochondria, Hsp60 associates with caspase-3 to form a complex that dissociates and releases from the mitochondria during apoptosis. In addition, Hsp60 accelerates the maturation of procaspase-3 through its ATP-dependent "foldase" activity. In addition to its role in protein folding, Hsp60 has also been implicated in immune function. In macrophages, its binding to the toll-like receptor-4 complex induces production of TNFα and nitric oxide and stimulation of a proinflammatory response. Thus, the protein folding function of Hsp60 is involved in mitochondrial protein folding in both normal and apoptotic cells, while release of Hsp60 during necrosis is thought to stimulate a proinflammatory response.

Alexa Fluor™ 647
Alexa Fluor™ 647 Dye is part of the BD red family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 653-nm and an emission maximum (Em Max) at 669-nm. Alexa Fluor 647 is designed to be excited by the Red laser (627-640 nm) and detected using an optical filter centered near 520-nm (e.g., a 660/20 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
