Alexa Fluor® 647 Mouse anti-Human Alkaline Phosphatase
Alexa Fluor® 647 Mouse anti-Human Alkaline Phosphatase

Flow cytometric analysis of Alkaline Phosphatase expression on human embryonic stem (ES) cells. H9 human ES cells (WiCell, Madison, WI) passage 45 grown in mTeSR™1 medium (StemCell Technologies) on BD Matrigel™ hESC-qualified Matrix (Cat. No. 354277) were harvested and stained with Alexa Fluor® 647 Mouse anti-Human Alkaline Phosphatase antibody (solid line) or Alexa Fluor® 647 mouse IgG1, κ isotype control (Clone MOPC-21, Cat. No. 557714, dashed line). Flow cytometry was performed on a BD LSR™ II flow cytometry system.

Alexa Fluor® 647 Mouse anti-Human Alkaline Phosphatase

Immunoflourescent staining of Alkaline Phosphatase on human embryonic stem (ES) cells. H9 human ES cells (WiCell, Madison, WI) passage 34 grown on irradiated mouse embryonic fibroblasts were fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655) and stained with Alexa Fluor® 647 Mouse anti-Human Alkaline Phosphatase monoclonal antibody (pseudo-colored red) at 5 μg/mL. Cell nuclei were stained with Hoechst 33342 (pseudo-colored blue). The images were captured on a BD Pathway™ 435 Cell Analyzer and merged using BD Attovision™ Software.

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.

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. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  3. An isotype control should be used at the same concentration as the antibody of interest.
  4. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
  5. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  6. 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.

B4-78

The B4-78 monoclonal antibody reacts with the tissue-nonspecific isozyme of alkaline phosphatase. Alkaline phosphatases are membrane-bound glycoproteins. Four isozymes of alkaline phosphatase exist in humans: placental, placental-like, intestinal, and liver/bone/kidney. Liver/bone/kidney alkaline phosphatase is also known as tissue-nonspecific alkaline phosphatase (TNAP). Human embryonic stem cells and embryonic carcinoma cells express high levels of tissue-nonspecific alkaline phosphatase that decrease upon differentiation. Genetic and biochemical studies suggest that TNAP plays a role in skeletal mineralization.

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.
