Alexa Fluor® 647 Mouse Anti-Nkx2.2
Alexa Fluor® 647 Mouse Anti-Nkx2.2
Flow cytometric analysis of Nkx2.2 expression in transfected human embryonic kidney cells. Nkx2.2-transfected 293-F cells were fixed and permeabilized with the BD Pharmingen™ Transcription Factor Buffer Set (Cat No. 562574) and stained with either Alexa Fluor® 647 Mouse IgG2b, κ Isotype Control (Cat. No. 557903, dashed line) or Alexa Fluor® 647 Mouse Anti-Nkx2.2 (solid line). The fluorescence histograms were derived from gated events with the forward and side light-scatter characteristics of intact 293-F cells. Flow cytometry was performed using a BD FACSCanto™ II Flow Cytometer System.

The nuclear counter-staining was with DAPI (pseudo-colored blue). The images were captured on a BD Pathway™ 435 Cell Analyzer and merged using BD Attovision™ software. Permeabilization with BD Perm/Wash™ Buffer (Cat No. 554723) or 0.1% Triton™ X-100 buffer is also suitable for use with this antibody.

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

Alexa Fluor® 647 Mouse Anti-Nkx2.2 effectively stains Nkx2.2-transfected 293-F cells when using the BD Pharmingen™ Transcription Factor Buffer Set (Cat. No. 562574). However, we recommend fixation with BD Cytofix™ Fixation Buffer (Cat. No. 554655) and permeabilization with BD Phosflow™ Perm Buffer III (Cat. No. 558050) for staining of untransfected 293-F cells.

74.5A5

The 74.5A5 monoclonal antibody specifically binds to Homeobox protein Nkx-2.2 (Nkx2.2), which is a transcription factor required for the differentiation of ventral neuronal populations in the central nervous system and endocrine cell populations in the pancreas and intestine. Within the pancreas, Nkx2.2 is expressed in many cell subsets and plays important roles in islet and β-cell differentiation and maturation. Mice with a homozygous disruption of the Nkx2-2 gene lack mature β cells and die shortly after birth with severe hyperglycemia. Similarly to the Nkx2.2-ablated mice, homozygous mutations in the human NKX2-2 gene have been described in diabetic patients and associated with the etiology of neonatal diabetes. The NKX2-2 gene is also a target of the Ewing sarcoma specific protein EWS-FLI. Nkx2.2 expression can be monitored in order to determine cell fate changes in cultures for the generation of human pluripotent stem cell-derived insulin-producing cells as well as oligodendrocyte progenitors.

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.
