Alexa Fluor® 647 Mouse Anti-Human CD222
Alexa Fluor® 647 Mouse Anti-Human CD222
Multiparameter flow cytometric analysis of CD222 expression by human leucocyte populations.        Left Panel - Surface Staining: Human whole blood was stained with Alexa Fluor® 488 Mouse Anti-Human CD3 antibody (Cat. No. 557694) and either Alexa Fluor® 647 Mouse IgG1, κ Isotype Control (Cat. No. 557732; Top Plots) or Alexa Fluor® 647 Mouse Anti-Human CD222 antibody (Cat. No. 565105; Bottom Plots). Erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899). Two-color flow cytometric dot plots showing the correlated expression of CD222 (or Ig Isotype control staining) versus side light-scattered signals (SSC) or CD3 were derived from gated events with the forward and side light-scatter characteristics of viable leucocytes (Left Plots) or lymphocytes (Right Plots), respectively.        Right Panel - Surface and Intracellular Staining: Human whole blood was treated with BD Phosflow™ Lyse/Fix Buffer (Cat. No. 558049) to lyse erythrocytes and fix cells. The leucocytes were then permeabilized with BD Perm/Wash™ Buffer (Cat. No. 554723) and stained with BD Horizon™ BV421 Mouse Anti-Human CD3 antibody (Cat. No. 562426/562427) and either Alexa Fluor® 647 Mouse IgG1, κ Isotype Control (Top Plots) or Alexa Fluor® 647 Mouse Anti-Human CD222 antibody (Bottom Plots). Two-color flow cytometric dot plots showing the correlated expression of CD222 (or Ig Isotype control staining) versus side light-scattered signals (SSC) or CD3 were derived from gated events with the forward and side light-scatter characteristics of intact leucocytes (Left Plots) or lymphocytes (Right Plots), respectively.        Flow cytometric analysis was performed using a BD LSRFortessa™ Cell Analyzer 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 to Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.

MEM-238

The MEM-238 monoclonal antibody specifically binds to CD222, which is also known as the Insulin-like growth factor 2 Receptor (IGF2R, IGF-II Receptor), Cation-independent mannose 6-phosphate receptor (CIMPR), or Mannose-6 phosphate receptor (M6PR). CD222 is ubiquitously expressed by a variety of cell types as a cell surface type I transmembrane glycoprotein. However, in the course of receptor trafficking between the cell surface and intracellular compartments, the majority of CD222 is found within cells. Cell surface CD222 functions as a multifunctional receptor that binds to a large number of extracellular ligands including acid hydrolases, insulin-like growth factors, latent TGF-β, leukemia inhibitory factor (LIF), proliferin, prorenin, plasminogen, and Herpes simplex virus. It regulates extracellular Insulin-like growth factor II (IGF-II/IGF-2) levels by binding and internalizing the growth factor for lysosomal degradation.  This effectively removes IGF-II from the circulation and tissues and thus prevents it from signaling through the growth-stimulatory Insulin-like growth factor I Receptor (IGF-1R, CD221) pathway. However, studies have reported that IGF-II may activate some cellular functions through CD222 as well. A soluble form of the CD222 extracellular region can also be detected in human serum and may play a role in regulating IGF-II activity. CD222 serves as a surface receptor for latent TGFβ and can complex with plasminogen and CD87, a urokinase-type plasminogen activator receptor, to activate latent TGF-β. CD222 also binds to a variety of Mannose 6-phosphate (M6P)-containing proteins, including extracellular and newly-synthesized lysosomal enzymes, and transports them to lysosomes.

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.
