1. A neutralizable epitope common to the envelope glycoproteins of ecotropic, polytropic, xenotropic, and amphotropic murine leukemia viruses
L H Evans, et al.J Virol. 1990 Dec;64(12):6176-83. doi: 10.1128/JVI.64.12.6176-6183.1990. PMID: 1700832
“An epitope common to all classes of murine leukemia viruses (MuLVs) was detected by reactivity of MuLVs with a rat monoclonal antibody (MAb) termed 83A25. The antibody is of the immunoglobulin G2a isotype and was derived after fusion of NS-1 myeloma cells with spleen cells from a Fischer rat immunized with a Friend polytropic MuLV. …In contrast, protein immunoblot and immunoprecipitation analyses established that the epitope reactive with MAb 83A25 resides in the envelope glycoproteins of the viruses. …The epitope served as a target for neutralization of all classes of MuLV with MAb 83A25.”
2. Detection of receptor-specific murine leukemia virus binding to cells by immunofluorescence analysis
M J Kadan, et al.J Virol. 1992 Apr;66(4):2281-7. doi: 10.1128/JVI.66.4.2281-2287.1992. PMID: 1312632
“By using the rat monoclonal antibody 83A25, which recognizes an epitope of the envelope gp70 molecule common to the different classes of MuLV, it is possible to analyse the binding of ecotropic, amphotropic, or xenotropic MuLV by using only a single combination of primary and secondary antibodies. The MuLV binding detected by this assay is envelope receptor specific and matches the susceptibility to infection determined for cells from a variety of species. The binding of amphotropic MuLV to NIH 3T3 cells was shown to be rapid, saturable, and temperature dependent. Chinese hamster ovary (CHO-K1) cells normally lack the ability to bind ecotropic virus and are not infectible by ecotropic vectors. Expression of the cloned ecotropic retrovirus receptor gene (Rec) in CHO-K1 cells confers high levels of ecotropic virus-specific binding and confers susceptibility to infection. Characterization of MuLV binding to primary cells may provide insight into the infectibility of cells by retroviruses and aid in the selection of appropriate vectors for gene transfer experiments.”
3. Growth factors increase amphotropic retrovirus binding to human CD34+ bone marrow progenitor cells
G M Crooks, et al.Blood. 1993 Dec 1;82(11):3290-7. PMID: 7694678
“The rat monoclonal antibody 83A25 recognizes an epitope common to the envelope glycoprotein of all classes of Moloney murine leukemia virus. Indirect fluorescent labeling of 83A25 allows flow cytometric analysis of specific virus-cell interactions and is an indirect measure of specific receptors. Using this assay, amphotropic virus binding to fresh CD34+ cells was minimal. However, when CD34+ cells were cultured with or without growth factors for 4 days, specific binding of amphotropic retrovirus was readily shown. Inclusion of interleukin-3 (IL-3), IL-6, and Steel factor in cultures increased the fluorescence associated with amphotropic virus binding by twofold to four-fold (mean fold increase 2.7 +/- 0.84). Virus binding to CD34+CD38- cells was shown only in those cells culture in IL-3, IL-6, and Steel factor. These results suggest that certain cytokines may cause an increase in the number and/or affinity of amphotropic receptors on primitive human hematopoietic cells. Upregulation of viral receptor expression may be one of the mechanisms by which cytokines enhance gene transfer into primitive BM cells.”
