PE Mouse Anti-Human ZBTB7B (ThPOK)
PE Mouse Anti-Human ZBTB7B (ThPOK)

Two-color flow cytometric analysis of ZBTB7B (Th-POK) expression in human peripheral blood mononuclear cells. PBMCs were surface stained with Alexa Fluor® 488 Mouse Anti-Human CD4 antibody (Cat. No. 557695).  The cells were then washed, fixed, and permeabilized using the BD Pharmingen™ Transcription Factor Buffer Set (Cat. No. 562574/562725) and stained with either PE Mouse IgG1, κ Isotype Control (Cat. No. 554680) or PE Mouse Anti-Human ZBTB7B (ThPOK) antibody. The two-color flow cytometric contour plots showing the correlated expression of ZBTB7B (ThPOK) [or Ig Isotype Control] versus CD4 were derived from gated events with the forward and side light-scatter characteristics of intact lymphocytes. Flow cytometric analysis was performed using a BD LSR Fortessa™ X-20 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 with R-PE under optimum conditions, and unconjugated antibody and free PE were 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. 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.

6/hcKrox

The 6/hcKrox monoclonal antibody specifically recognizes human Th Inducing POZ-Kruppel Factor (ThPOK) which is also known as, cKrox or hcKrox. ThPOK is encoded by ZBTB7B (Zinc finger and BTB domain-containing protein 7B) and is a member of the POK/ZBT family of transcription regulators that play roles in lymphocyte development and the regulation of type I collagen genes. ThPOK expression is upregulated during the differentiation of CD4+ T helper cells but not CD8+ T cells.  It indirectly increases the expression of CD4 in developing T cells by antagonizing Runx-3-mediated CD4 repression. ThPOK is also expressed in NKT and γδ T cells.

PE
R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
