APC Mouse Anti-Human GPR56
APC Mouse Anti-Human GPR56
Multicolor flow cytometric analysis of GPR56 expression on human peripheral blood lymphocytes. Whole human blood was stained with PE Mouse Anti-Human CD56 antibody (Cat. No. 555516/561903) and either APC Mouse IgG1, κ Isotype Control (Cat. No. 554681; Left Plot) or APC Mouse Anti-Human GPR56 antibody (Cat. No. 567612/567613; Right Plot). Erythrocytes were lysed with BD FACS™ Lysing Solution (Cat. No. 349202). The bivariate pseudocolor density plots showing either GPR56 [or Ig isotype control] staining versus CD56 were derived from gated events with the forward and side light-scatter characteristics of intact lymphocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer 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 to the dye under optimum conditions and unconjugated antibody and free dye were removed.

Recommended Assay Procedures

BD® CompBeads can be used as surrogates to assess fluorescence spillover (Compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells.  However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

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. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  6. This APC-conjugated reagent can be used in any flow cytometer equipped with a dye, HeNe, or red diode laser.
  7. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  8. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
  9. Species cross-reactivity detected in product development may not have been confirmed on every format and/or application.

CG4.rMAb

The CG4.rMab is a recombinant monoclonal antibody that was derived from CG4 hybridoma cells. The CG4.rMab specifically binds to human G-protein coupled receptor 56 (GPR56) like the conventional CG4 antibody and performs like the CG4 antibody when used to stain cells and analyze them by flow cytometry. GPR56 is also known as adhesion G-protein coupled receptor G1 (ADGRG1), or TM7XN1. GPR56 is a ~15kDa G protein-coupled receptor encoded by ADGRG1 which belongs to the adhesion-GPCR family that comprises 33 members in human. The extracellular region contains a mucin-like domain followed by a membrane proximal GPCR-autoproteolysis inducing (GAIN) domain, seven transmembrane regions and a cytoplasmic tail. The constitutive self-cleavage at the proteolytic site gives rise to a membrane spanning (C-terminal fragment or CTF) and an extracellular (N-terminal fragment or NTF) subunit that remain noncovalently bound, leading to the expression of a heterodimeric receptor at the cell surface. GPR56 is widely expressed with the highest levels of messenger found in the brain, heart, and thyroid gland. Recently, GPR56 was found to be variably expressed on platelets, cytotoxic NK cells and T lymphocytes including CD4+, CD8+, and γδ T cells. It was shown that GPR56 functions as an inhibitory receptor on NK cells through interaction with CD81. While GPR56 NTF associates with Tissue transglutaminase 2 and Collagen III (α-1), GPR56 CTF can recruit Gα proteins leading to the activation of mTOR and RhoA signaling pathways. GPR56 has been implicated in cell-cell interactions, adhesion, migration, and regulation of cell proliferation and survival of various cell types. New evidence also shows a role of GPR56 in tumor progression. Recently, the CG4 antibody was found to activate GPR56 in melanoma cells leading to an increase of IL-6 secretion, in a CD9/CD81-dependent manner.

APC
Allophycocyanin (APC), is part of the BD family of phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 651 nm and an emission maximum (Em Max) at 660 nm. APC is designed to be excited by the Red (627-640 nm) laser and detected using an optical filter centered near 660 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.
