Alexa Fluor® 647 Mouse Anti-Human Cytokeratin
Alexa Fluor® 647 Mouse Anti-Human Cytokeratin

Flow cytometric analysis of cytokeratin expression in human SK-BR-3 cells. Cells from the human SK-BR-3 (Breast adenocarcinoma, ATCC HTB-30) cell line were incubated with 1X BD FACS™ Lysing Solution (Cat. No. 349202), permeabilized with BD FACS™ Permeabilizing Solution 2 (Cat. No. 340973/347692), and washed with BD Pharmingen™ Stain Buffer (FBS) (Cat. No. 554656). The cells were then stained with either Alexa Fluor® 647 Mouse Anti-Human Cytokeratin antibody (Cat. No. 563614; solid line histogram) or Alexa Fluor® 647 Mouse IgG2a, κ Isotype Control (Cat. No. 557715; dashed line histogram). The fluorescence histograms were derived from gated events with the forward and side light-scatter characteristics of intact cells. Flow cytometric analysis was performed using a BD™ LSR II Flow Cytometer System.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. 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.

Recommended Assay Procedures

Note: The CAM5.2 antibody can also be used to stain cells that have been fixed and permeabilized using  BD Cytofix™ Fixation Buffer (Cat. No. 554655) and BD Perm/Wash™ Buffer (Cat. No. 554723).

Product Notices

  1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  5. The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.
  6. Alexa Fluor® is a registered trademark of Molecular Probes, Inc., Eugene, OR.
  7. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
  8. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

CAM5.2

The CAM5.2 monoclonal antibody specifically recognizes cytokeratin having a primary reactivity with human keratin proteins that correspond to Moll's peptides #7 (48 kDa) and #8 (52 kDa). Cytokeratin 7 and 8 are type II cytoskeletal keratins. These cytoskeletal proteins provide structural integrity for epithelial cells and may serve other functions as well. They are expressed in epithelia cells that comprise normal human tissues. Although these cytokeratins are not normally expressed in stratified squamous epithelium, they may be expressed in some squamous cell carcinomas. The CAM 5.2 antibody stains most epithelial-derived tissue, including liver, renal tubular epithelium, and hepatocellular and renal cell carcinomas.

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.
