Kelker H, Schlesinger D, Valentine F
J Immunol . 1994 Apr; 152(8):4139-48. PMID: 8144976
An HIV-1 envelope protein gp120-derived monomeric peptide (amino acid residues 419-439) and its homologous multiple chain peptide (MCP) construct were compared for immunogenicity in mice. The Abs stimulated by the...

Kelker H, Seidlin M, Vogler M, Valentine F
AIDS Res Hum Retroviruses . 1992 Aug; 8(8):1355-9. PMID: 1466956
A comparison of the proliferative responses of lymphocytes to human immunodeficiency virus (HIV) antigens from long-term, seronegative heterosexual partners of HIV-infected subjects, from normal unexposed controls and from healthy seropositive...

Kelker H, Oppenheim J, Aggarwal B, Stevenson H, Vilcek J
Int J Cancer . 1985 Jul; 36(1):69-73. PMID: 3874835
Cultures of human peripheral blood leukocytes (PBL) induced with phytohemagglutinin (PHA) and the phorbol ester 12-0-tetradecanoylphorbol 13-acetate (TPA) produced two types of cytotoxic proteins, indistinguishable in the in vitro assay...

Kelker H, Le J, Rubin B, Yip Y, Nagler C, Vilcek J
J Biol Chem . 1984 Apr; 259(7):4301-4. PMID: 6423641
Immune interferon (IFN-gamma), endogenously labeled with [35S]methionine, was produced in human peripheral blood lymphocyte cultures stimulated with 12-O-tetradecanoylphorbol-13-acetate and phytohemagglutinin. 35S-IFN-gamma, immunoprecipitated from the crude culture fluid with a monoclonal...

Yip Y, Kelker H, Le J, Rubin B, Rinderknecht E, Aggarwal B, et al.
J Exp Med . 1984 Mar; 159(3):828-43. PMID: 6421983
Crude preparations of interferon (IFN)-gamma derived from human peripheral blood leukocyte (PBL) cultures induced with 12-O-tetra-decanoylphorbol-13-acetate (TPA) and phytohemagglutinin (PHA) were more cytotoxic to HeLa cells than partially purified nautral...

Le J, Rubin B, Kelker H, Feit C, Nagler C, Vilcek J
J Immunol . 1984 Mar; 132(3):1300-4. PMID: 6420463
Monoclonal antibody GIF-1 was found to neutralize human natural immune interferon (IFN-gamma), but not Escherichia coli-derived recombinant IFN-gamma. In addition, GIF-1 antibody failed to immunoprecipitate 125I-labeled recombinant IFN-gamma, whereas it...

Yip Y, Kelker H, Pearlstein K, Urban C, Vilcek J
Cell Immunol . 1983 Jul; 79(2):389-95. PMID: 6409425
Previous studies showed that the tumor-promoting phorbol ester 12-O-tetradecanoylphorbol 13-acetate (TPA) and several structurally related tumor-promoting compounds stimulate lymphocytes to produce immune interferon (IFN-gamma) and interleukin 2 (IL-2). This study...

J Biol Chem . 1983 Jul; 258(13):8010-3. PMID: 6305965
Highly purified human interferon (IFN)-gamma was treated with a preparation of mixed glycosidases in order to evaluate the effect of carbohydrate depletion on its biological activity, isoelectric point, and molecular...
