Amino acid adsorption and protein synthesis in Escherichia coli (1955)

Britten, R. J., Roberts, R. B., French, E. F.

Treponema pallidum cultivation is facilitated by substitution of methylprednisolone acetate suspension for hydrocortisone administration during rabbit testicular infection. Methylprednisolone...

Studies on Memory: Distribution of Peptidyl-Puromycin in Subcellular Fractions of Mouse Brain

Flexner, L. B., Gambetti, P., Flexner, J. B., Roberts, R. B.

Previous experience has led us to suggest that sustained blockage of memory in mice upon administration of puromycin is caused by the persistence of peptidyl-puromycin at synapses. The block can be...

Production of and in vitro response to interleukin 2 in the acquired immunodeficiency syndrome.

Murray, H W, Welte, K, Jacobs, J L, Rubin, B Y, Mertelsmann, R, Roberts, R B

To test the hypothesis that deficient interleukin 2 (IL-2) secretion may underlie the impaired capacity of T cells from patients with Acquired Immunodeficiency Syndrome (AIDS) and the AIDS-related...

Gonococci-human polymorphonuclear leukocyte interactions: metabolic studies associated with attachment and ingestion.

Krieger, A G, Schiller, N L, Roberts, R B

Utilizing monolayers of human polymorphonuclear leukocytes, optimal conditions for attachment and ingestion of Neisseria gonorrhoeae were determined. Both attachment and ingestion were optimal at 36...

A Model for the Mechanism of Enzyme Induction

Roberts, R. B., Britten, R. J., McClure, F. T.

A sequence of reactions is postulated from which are derived equations describing the time course of enzyme induction. The model also yields the observed effect of the inducer concentration on the...

The Synthesis of Ribosomes in E. coli: III. Synthesis of Ribosomal RNA

McCarthy, B. J., Britten, R. J., Roberts, R. B.

Techniques of chromatography on columns of DEAE1 cellulose and sedimentation analysis through a sucrose gradient have been used to study the flow of C14-uracil label through precursors to completed...

The Synthesis of Ribosomes in E. coli: IV. The Synthesis of Ribosomal Protein and the Assembly of Ribosomes

Britten, R. J., McCarthy, B. J., Roberts, R. B.

The incorporation of C14 leucine into the protein moiety of ribosomes has been studied as a sequel to the studies of ribosomal RNA synthesis. In contrast to the latter studies, labeled leucine is...
