[1] The Imager for Sprites and Upper Atmospheric Lightning (ISUAL) on the Taiwanese FORMOSAT-2 (formerly ROCSAT-2) spacecraft is the first global observatory of transient luminous events (TLEs). During the first 4 months of operation a large number of elves were observed. Elves are obvious with their far ultraviolet (FUV) signature that is less attenuated(More)
[1] We report coordinated measurements of lightning and resulting sprites using ground-level magnetic field sensors (<0.1 Hz to 30 kHz bandwidth) and the ISUAL instrument on the FORMOSAT-2 satellite. These measurements demonstrate two distinct elements of the connection between the radio and optical emissions. First, the quasi-static magnetic field(More)
A specific and high throughput 96-well format bioassay for recombinant human relaxin (rhRLX) has been developed using human endometrial cells (NHE cells). rhRLX caused a time- and dose-dependent stimulation of cyclic AMP (cAMP) with 1/2 maximal activity of 3.56 +/- 0.65 ng/ml (n = 30). The range of the standard curve was 0.39 to 25 ng/ml with interplate(More)
[1] The ISUAL gigantic jets (GJs) are categorized into three types from their generating sequence and spectral properties. Generating sequence of the type I GJs resembles that reported previously; after the fully developed jet (FDJ) established the discharge channel, the ISUAL photometers registered a peak that was from a return‐stroke‐like process. The(More)
These investigations were directed at furnishing information on the essential structural features of the cold-insoluble globulin of human plasma. Amino acid and carbohydrate analyses showed that it is a glycoprotein (1.2% sialic acid, 1.8% hexose, 2.1% hexosamine) containing all of the amino acids usually found in proteins. Circular dichroic spectral(More)
The quantitation of human GH in a serum sample is not consistent among various commercially available immunoassays. We measured serum GH concentrations with four RIAs [Cambridge, Kallestad, National Hormone and Pituitary Program, and Radioassay Systems Laboratories (RSL)] and two immunoradiometric assays (IRMAs; Hybritech and Nichols). Serum GH(More)
When the serum concentration of the culture medium is below 0.7 per-cent, 3T3 mouse cells lose most of their large external transformation sensitive (LETS) protein at the cell surface, Subsequent addition of epidermal growth factor results in the reappearance of massive fibrillar LETS protein networks on the surface of conluent 3T3 cells. Thirteen other(More)
Two methods, High-Performance Receptor Binding Chromatography (HPRBC) and Cell Proliferation (CP), have been developed as alternatives to the classical hypophysectomized rat weight gain bioassay for the determination of potency for recombinant human growth hormone (rhGH). In the HPRBC assay, rhGH is combined with an excess of the soluble extracellular(More)
A simple and non-radioactive complement-dependent cytotoxicity assay was developed to determine the relative potency of an anti-CD20 mAb, IDEC-C2B8. The assay measures the relative number of viable cells based on the uptake and metabolism of the redox dye, Alamar blue. A linear relationship between the relative fluorescence unit generated and the number of(More)
