Identification of a beta2-adrenergic receptor in mammalian epidermis
(Elsevier, 1980-01-01)
The presence of a beta2-adrenergic receptor in the epidermis has been demonstrated, based on the following pieces of information: (1) the addition of salbutamol, a beta2-agonist, to slices of epidermal tissue increased the ...
Cycloaddition of vinyl aziridines with unsaturated substrates. A novel rearrangement of an unsaturated nitro compound.
(Elsevier, 1981)
Vinylaziridine undergoes reaction with electrophilic acetylenes and olefins to produce 7-membered azepine derivatives. With [beta]-nitro-styrene however, a novel rearrangement occurs, presumably via an ene reaction to ...
Interaction of tRNA transcription factors with satellite I DNA from Xenopus laevis
(Elsevier, 1988-02-29)
A cloned repeat of Xenopus laevis satellite I DNA was tested for the ability to form stable complexes with tRNA transcription factors in vitro. In template exclusion studies, the satellite I DNA competed efficiently with ...
Comments on rarity and chaos, Thomas D. Rogers, math. biosci. 72:13-18 (1984)
(Elsevier, 1985-03)
A specific Enzyme-Linked Immunosorbent Assay (ELISA) for the determination of human C5a antigen
(Elsevier, 1983-09-16)
An enzyme-linked immunosorbent assay has been developed to detect human C5a antigen. This ELISA methodology has been shown to be a highly sensitive technique capable of detecting C5a antigen concentrations below 10 ng/ml. ...
Immunochemical studies on the binding specificity of the blood group Leb specific lectin Griffonia simplicifolia IV
(Elsevier, 1983-05)
The specificity of the Griffonia simplicifolia IV (GS-IV) lectin was studied by quantitative precipitin and quantitative precipitin inhibition assays. The lectin precipitated most strongly with a human H,Leb blood group ...
Development and characterization of cold-adapted viruses for use as live virus vaccines
(Elsevier, 1985-12)
Representative viruses from twelve RNA and two DNA virus genera have been successfully adapted to growth at sub-optimal temperature (cold-adapted). In almost every case, there was a correlation between acquisition of the ...
Semisyngeneic hybrid resistance to murine teratocarcinoma cells
(Springer-Verlag, 1980-02)
Resistance to two cultured lines of murine embryonal carcinoma was studied in F 1 hybrids constructed between the tumor-syngeneic mouse strain 129/J and several allogeneic strains. Three of four such hybrid strains were ...
