SummaryPolyene antibiotics are agents known to damage cell membranes. The hexaene antibiotic, mediocidin, was used in an attempt to introduce a mammalian virus (Mengo) into normally nonpermissive ICR 2A haploid frog cells. Although no infectious viru

We have characterized two components of DNA isolated from mouse L-M cell nuclei. These components, designated as HMW (high molecular weight) and VHMW (very high molecular weight) DNA, were characterized by rate zonal sedimentation, agarose gel electr

NAD was covalently linked to Sepharose-4B using a 6 carbon spacer. Sterile, dialyzed spent culture medium containing 100 Lf/ml of diphtheria toxin or material concentrated by (NH4)2SO4 precipitation containing 1500 Lf/ml, was chromatographed on a col

The response to diphtheria toxin of two sensitive cell lines, KB and HeLa, was investigated. Inhibition of the incorporation of radioactively labeled amino acids into protein was the earliest detectable effect of diphtheria toxin. It was observed tha

SummaryL strain fibroblasts were grown in medium 199P containing estrone-16-C14 and estradiol-16-C14 at a concentration ranging from 10-7 to 10-5 M. These cells did not convert either steroid into water soluble conjugates in 72 hours. The estradiol i

Diphtheria toxin splits into two fragments when heated at 100 C for 10 min in a phosphate buffer. The separated fragments have molecular weights of 24,000 and 39,000, respectively. These molecular weights are similar to those of the A and B fragments

The effect of varying the Na + to K + ratio has been studied in relation to the regulation of amino acid accumulation, protein synthesis and cell growth in LM-strain mouse fibroblasts. Amino acid accumulation and protein synthesis in these cells was

SummaryThe incidence of cell damage in L-M cell cultures exposed to DEAE-dextran increased with an increase in the concentration of the polycation. Poly I:C alone exerted a toxic effect which could be neutralized by 10 μg DEAE-dextran/ml. Cytotoxici

SummaryThe adsorption of mengovirus to L-M cells is inhibited either directly by DEAE-dextran or by substances released into culture media from cells exposed to DEAE-dextran and DEAE-dextran combined with poly I:C. Therefore, preparations containing
