Factors affecting anserine and carnosine levels in skeletal muscles of various animals
(Elsevier, 1976)
1. 1. Analytical procedures for anserine, carnosine and related histidine compounds in skeletal muscles are given.2. 2. The anserine/carnosine ratio in the skeletal muscles of the rat increases with age, cortisone injection ...
Kinetic parameters for the binding of p-nitrophenyl [alpha]--mannopyranoside to concanavalin A
(Elsevier, 1976-02)
Binding of the chromogenic ligand p-nitrophenyl [alpha]--mannopyranoside to concanavalin A was studied in a stopped-flow spectrometer. Formation of the protein-ligand complex could be represented as a simple one-step ...
Cooperative effects of bacterial mutations affecting [lambda] N gene expression : I. Isolation and characterization of a nusB mutant
(Elsevier, 1976-08)
We report the isolation and characterization of an Escherichia coli mutant which limits the growth of phage [lambda] by inhibiting the expression of the N gene regulatory function. The mutation involved maps near minute ...
Esterification of hemins with trimethyloxonium tetrafluoroborate
(Elsevier, 1976-11)
A procedure has been developed for the methylation of hemins using trimethyloxonium tetrafluoroborate. The method is rapid and selective for carboxyl groups, and it can be used to methylate polar and nonpolar hemins under ...
The developmental pattern of homologous and heterologous tRNA methylation in rat brain differential effect of spermidine
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1976-08)
Using S -adenosyl- L -[Me- 14 C] methionine, rat cerebral cortex methyltransferase activity was determined during the early postnatal period in the absence of added Escherichia coli tRNA and in its presence. [Me- 14 C] ...
Tissue graft rejection in mice
(Springer-Verlag; Springer-Verlag New York Inc., 1976-12)
A liver-slice to kidney-bed grafting system was used to study the course of rejection of a specific tissue across various genetic barriers in inbred strains of mice. Rejection or survival, scored histologically at various ...
Aldonate coupling, a simple procedure for the preparation of carbohydrate-protein conjugates for studies of carbohydrate-binding proteins
(Elsevier, 1976-08)
Aldonate coupling a new, high-yield method for conjugation of reducing oligosaccharides to proteins is described. It involves oxidation of the oligosaccharides to their corresponding aldonic acids followed by coupling to ...
Competition for the in vitro binding of radioiodinated human follicle-stimulating hormone in reptilian, avian, and mammalian gonads by nonmammalian gonadotropins
(Elsevier, 1976-11)
Radioiodinated human FSH (125I-hFSH) was used to study the specificity of the gonadotropin binding sites of various reptilian, avian, and mammalian gonadal tissues by examining competitive interactions with several ...
Uniformity in the clonal repertoire for the immune response to phosphorylcholine in mice
(WILEY-VCH Verlag GmbH, 1976-10)
A comparison of the clonal nature of the immune response to phosphorylcholine (PC) was made in nine different inbred mouse strains. Quantitative idiotypic analysis showed that anti-PC antibodies from each strain were ...
