Photoreflectance of InSb at the E1 and E1 + Δ1 transitions

Solid State Communications, 1994
Abstract The Photoreflectance at high interband transitions ( E 1 and E 1 + Δ 1 ) is obtained at 8 K for InSb bulk samples. For a p -type sample, the lineshape is well reproduced by Aspens third derivative model, while for an undoped sample, the photoreflectance spectra is better reproduced by a first derivative of an exciton lineshape ...

Fluorescence of prostaglandin E1

Analytical Chemistry, 1968
The chemical structure of PGE1 (prostaglandin E1) is diagrammed. Because this structure suggested the possibility of several resonance forms of the molecule a study was undertaken to determine their possible fluorescence. The laboratory procedures involved are explained. Increased concentrations of PGE1 were found to produce increased fluorescence.

Purification of E1 and E1-Like Enzymes

2005
Ubiquitin-activating enzyme is the archetype for a family of enzymes catalyzing the ATP-coupled activation of ubiquitin and other class 1 ubiquitin-like proteins required for their subsequent conjugation to cellular targets. The general physical and mechanistic features of the E1 family appear well conserved.

Prostaglandin E1: A review

Prostaglandins, Leukotrienes and Essential Fatty Acids (PLEFA), 1988
Work on the structure of prostaglandin E1 (PGE1), isolated from natural sources, was completed 25 years ago (1). Shortly after, methods for the chemical synthesis of PG with their natural configuration were developed in the laboratories of the UpJohn Company (2) and of E. J. Corey (3) and, by the late sixties, PGE1 became widely available.
