Description
The Zt/g4 monoclonal antibody specifically binds to RON, which is also known as CD136, Macrophage-stimulating protein receptor (MSP-Receptor, MSP-R), Macrophage stimulating 1 receptor (c-met-related tyrosine kinase) (MST1R), or Protein-tyrosine kinase 8 (PTK8). RON is a type I transmembrane glycoprotein that belongs to the receptor tyrosine kinase family. It is expressed on cells as a disulfide-linked heterodimer. RON is expressed on macrophages, keratinocytes, erythroblasts and epithelial cells from the skin, lung, kidney, liver, intestine, colon, and bone marrow. RON reportedly regulates many physiological processes including the survival, migration, differentiation, and effector functions of a variety of cell types including epithelial cells, and macrophages. RON binds Macrophage stimulating protein (MSP). Overexpression of RON may contribute to the malignant transformation of epithelial cells.
Bead-based compensation or unmixing controls, such as BD® CompBeads or BD™ SpectraComp™, can be used as surrogates to assess fluorescence spillover when bound to fluorochrome-conjugated antibodies. Although these beads have spectral properties similar to cells, variations in spectral emission may occur, resulting in differing spillover values compared to biological controls. Therefore, it is considered best practice to compare the spillover obtained from cells and bead-based controls when using BD® CompBeads or BD™ SpectraComp™ for the first time, to ensure they are appropriate for the intended application.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions that minimize unconjugated dye and antibody. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

2. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
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. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
5. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
6. When using high concentrations of antibody, background binding of this dye to erythroid fragments produced by ammonium chloride-based lysis, such as with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899), has been observed when the antibody conjugate was present during the lysis procedure. This may cause nonspecific staining of target cells, such as leukocytes, which have bound the resulting erythroid fragments. This background can be mitigated by any of the following: titrating the antibody conjugate to a lower concentration, fixing samples with formaldehyde, or removing erythrocytes before staining (eg, gradient centrifugation or pre-lysis with wash). This background has not been observed when cells were lysed with BD FACS™ Lysing Solution (Cat. No. 349202) after staining.
7. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
8. An isotype control should be used at the same concentration as the antibody of interest.
9. Please observe the following precautions: We recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to protect exposure of conjugated reagents, including cells stained with those reagents, to any room illumination. Absorption of visible light can significantly affect the emission spectra and quantum yield of tandem fluorochrome conjugates.
10. Clones without a listed workshop have not been investigated in an HLDA workshop to receive a CD nomenclature. We use “CD” provisionally when our internal testing indicates that this clone binds to the same CD antigen as workshopped clones.

13. Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.
