Carbohydrates are among the potential materials for molecular devices, since they are abundant natural resources. However, their rigidity has restricted their use for movable devices. Hinge sugars, 2,4-diamino-2,4-dideoxy-xylopyranosides, shed light on the use of carbohydrates as movable components, as demonstrated by the motion by which all four equatorial(More)
Serum from a patient (KK) with IgG2-lambda myeloma was shown to contain multiple paraproteins corresponding to an IgM-lambda monoclonal protein (MMP), a lambda-type Bence Jones protein (BJP), and a 30 kDa component in addition to the IgG2 myeloma protein (GMP). These proteins possessed common idiotypic determinants, as judged by their monoclonal reactivity(More)
The effect of human C-reactive protein (CRP) on macrophage function was studied in an assay of superoxide anion (O2-) production. Peritoneal exudate macrophages (PEM) of guinea pigs exposed in vitro to various doses of CRP for 72 hr resulted in the development of O2- production dose-dependently, measured by increases in superoxide dismutase-inhibitable(More)
Attempts were made to induce azobenzenearsonate (ABA)-specific helper cell responses in A/J mice. These were measured by an increase in TNP plaque-forming cells following administration of the double hapten conjugate ABA-bovine serum albumin-TNP. Immunization with ABA coupled homologous immunoglobulin or spleen cells produced ABA-specific help only when the(More)
Immunization of Lewis rats with azobenzenearsonate-N-acetyl-L-tyrosine (ABA-tyr) in complete Freund's adjuvant (CFA), produces a hapten-specific helper T cell response measured by an increase in plaque forming cells (PFC) against a different hapten. The response seen is primarily direct (IgM) PFC unless B cells are primed by injection of trinitrophenylated(More)
Contact hypersensitivity to picrylchloride was induced in guinea pigs by the subcutaneous injection of heteroantigenic components which were isolated by antibody immunoadsorbent from soluble epidermal proteins of picrylchloride painted guinea pigs. The injection of non-heterantinenic components obtained from the picrylchloride treated guinea pig epidermis(More)
