Alexa Fluor® 647 Mouse anti-PDPK1 (pS241)
Alexa Fluor® 647 Mouse anti-PDPK1 (pS241)
Analysis of PDPK1 (pS241) in human peripheral blood mononuclear cells (PBMC).  PBMC were either treated with calyculin A plus okadaic acid for 30 minutes at 37ºC or untreated.  The cells were fixed with pre-warmed BD Phosflow™ Lyse/Fix Buffer (Cat. No. 558049) for 15 minutes at 37ºC and permeabilized with BD Phosflow™ Perm Buffer III (Cat. No. 558050) on ice for 30 minutes.  LEFT PANEL:  The treated (solid line) and untreated (dashed line) PBMC were stained with Alexa Fluor® 647 Mouse IgG1, κ isotype control mAb MOPC-21 (Cat. No. 557783).  RIGHT PANEL:  The treated (solid line) and untreated (dashed line) PBMC were stained with Alexa Fluor® 647 Mouse anti-PDPK1 (pS241).  The data demonstrates that the phosphorylation of PDPK1 is constitutive in all PBMC and that the level of phosphorylation increases when phosphatase activity is inhibited by the treatment.  Flow cytometry was performed on a BD FACSCalibur™ flow cytometry system.

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.

J66-653.44.17

The serine/threonine kinase 3-Phosphoinositide-Dependent Protein Kinase-1 (PDPK1, also known as PDK1) contributes to the activation of many important kinases in the insulin and IGF-1 signaling pathways.  It acts downstream of phosphatidylinositol 3-kinase (PI3-kinase) to phosphorylate residues in the activation loops of many cellular kinases, including protein kinase B (PKB/Akt), PKC isoforms, p70 S6 kinase, and PDPK1 itself.  The autophosphorylation of PDPK1 at serine 241 (S241) has recently been suggested to play a role in the regulation of PDPK1.  It has been proposed that PDPK1 activity plays a key role in the regulation of various cellular events such as cell proliferation, differentiation, and apoptosis.

The J666-653.44.17 monoclonal antibody recognizes the phosphorylated S241 in the activation loop of human PDPK1.  The orthologous phosphorylation site in mouse and rat PDPK1 is S244.

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 670-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.
