The rapid, quantitative release of astaxanthin and other carotenoids from the yeast Phaffiarhodozyma is described. Hashed cells are ruptured with dimethylsulfoxide (DMSO) and carotenoids extracted into an organic solvent. Extraction and spectrophotom

Several Togaviridae of the alphavirus and flavivirus genera agglutinate trypsinized human group 0 erythrocytes (THOE) (Shortridge and Hu, 1976). Haemagglutinin titers of Semliki Forest virus (SFV) and Japanese encephalitis virus (JEV) measured with T

An assay for proteins in solution is described that depends on the conversion of Coomassie brilliant blue G250 in dilute acid from a brownish-orange to an intense blue color. As soon as the dye solution is mixed with a protein sample, the absorbance

Treatments of isolated L929 cell nuclei with MuIFN-β reduced the energy-dependent ef flux of 3H-RNA from these nuclei in a dose-dependent manner. These observations provide evidence for a direct physiological effect of IFN on the cell nucleus.

Purified natural and recombinant murine gamma interferons (MuIFN-gamma) bind at 4 degrees C to cultured L929 mouse fibroblasts with comparable receptor-binding affinity (Kd = 9 x 10(-10) M). Both 125I-labeled MuIFNs are rapidly internalized by cells

An electron microscopic technique employing postembedding immunolabeling was used to identify unmodified, intracellular MuIFN-beta molecules. The MuIFN-beta was rapidly internalized by receptor-dependent endocytosis and within three minutes a majorit

The production of neuraminidase by the recombinant influenza virus X7(F1) in human monkey, rabbit, hamster, mouse, and chicken cell cultures is inhibited by interferon. Described is a new enzyme assay for neuraminidase that can be applied to the bioa

Extracts of cells treated with purified interferon discharge the amino acid previously esterified to viral RNA but fail to affect aminoacylated transfer RNA. A similar activity is also present in c...

Human immune interferon (IFN-gamma) differs from leukocyte interferon (IFN-alpha) and fibroblast interferon (IFN-beta) in cell origin, inducing agents, physical and biological properties and amino acid sequence. These differences have led to interest

Radioiodinated mouse interferon-beta (125I-MuIFN-beta) bound with high affinity (Kd = 9.8 X 10(-10) M) to plasma membrane of L929 murine fibroblasts (4-6 X 10(3) receptor sites per cell). The binding was saturable and inhibited by a 100-fold excess o
