A novel 21 kDa protein (p21) was detected in sera of patients with urogenital tumors by ELISA, using rabbit polyclonal antibodies generated against the p21 polypeptide. Eight out of 11 patients (72%) exhibited a 2-5 fold increase in pre-treatment p21

Immunoblot analysis using antibody specific to yeast ras-related protein Yp20 revealed a 21kDa protein associated with HeLa cell chromatin which immunologically cross-reacted with this ras-related protein. The 21kDa protein can be rapidly released fr

A Saccharomyces cerevisiae strain which contains both the “killer character” and a ts mutation in the initiation of nuclear DNA synthesis ( cdc4 ) was studied. Incubation of this strain at the restrictive temperature caused a 3–4 fold increase

The effect of ionic strength on the transcription of phage T4 DNA by endogenous RNA polymerase has been examined in a DNA-enzyme-membrane system. Using the above system and competition hybridization studies it is shown that (1) addition of monovalent

Two micrometer minichromosomes from Saccharomyces cerevisiae were isolated without detergent using metrizamide gradients. 2 μm minichromosomes showed a lower density in metrizamide gradients relative to genomic chromatin. Our results suggest a lower

Unfixed 2-μm minichromosomes from Saccharomyces cerevisiae may be isolated uncontaminated by genomic DNA by banding isopycnically in metrizamide [2-(3-acetamido-5- N -methylacetamido-2,4,6-triiodobenzamido)-2-deoxy- d -glucose[ according to the prot

Nonpermissive host cells infected with phage T4 mutants in genes 52, 39, and 58 through 61 are shown to form short intracellular single-stranded deoxyribonucleic acid in contrast to wild-type infected cells, which form dimers and trimers of T4 genome

The T4 amber mutant N130 in gene 46 produces, upon infection of a nonpermissive host, about 10 times more phage equivalent of deoxyribonucleic acid (DNA) than viable phage particles. Intracellular DNA is shorter than its mature phage counterpart and

Messenger ribonucleic acid (mRNA) preparations from T4-infected cells formed in the presence or absence of putrescine have been characterized and compared. Hybrid competition experiments indicate that these mRNA molecules are derived from distinct ge
