PE Mouse Anti-Human Transferrin R (CD71)
PE Mouse Anti-Human Transferrin R (CD71)
Flow cytometric analysis of Transferrin R (CD71) expression on activated human peripheral blood mononuclear cells (PBMC). Human PBMC were stimulated for 3 days with Phytohemagglutinin (PHA). The cells were harvested, preincubated with Human BD Fc Block™ (Cat. No. 564219/564220), and then stained with either PE Mouse IgG1, κ Isotype Control (Cat. No. 554680; dashed line histogram) or PE Mouse Anti-Human Transferrin R (CD71) antibody (Cat. No. 566722/566723; solid line histogram). BD Via-Probe™ Cell Viability 7-AAD Solution (Cat. No. 555815/555816) was added to cells right before analysis. The fluorescence histogram showing CD71 expression (or Ig Isotype control staining) was derived from gated events with the forward and side light-scatter characteristics of viable (7-AAD-negative) activated human peripheral mononuclear cells. Flow cytometry and data analysis were performed using a BD FACSCelesta™ Flow Cytometer System and FlowJo™ 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 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. An isotype control should be used at the same concentration as the antibody of interest.
  3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  4. 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.
  5. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

OKT9

The OKT9 monoclonal antibody specifically binds to CD71 which is also known as the transferrin receptor (TFR or Transferrin R). CD71 (Transferrin R) is a type II transmembrane glycoprotein that is encoded by TFRC (transferrin receptor) which belongs to the Transferrin receptor family.  It is expressed on cells as a disulfide-linked homodimer comprised of ~95 kDa monomers. CD71 is expressed on early thymocytes as well as activated lymphocytes, monocytes, macrophages, brain endothelium, and most proliferating cells. The transferrin receptor is also present on early erythroid cells but is lost as reticulocytes differentiate into mature erythrocytes. CD71 is lowly expressed on normal resting lymphocytes and is upregulated during lymphocyte responses to antigens or mitogens. The transferrin receptor is essential for iron transport into proliferating cells. Through an endocytic pathway, the transferrin receptor mediates cellular iron uptake by binding and internalizing iron that is bound to transferrin. After releasing iron within the low pH endosomal environment, transferrin and its receptor can be recycled to the cell surface.

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.
