An azophenolic colorimetric reagent for use in enzyme-linked immunosorbent assays.
(Elsevier: Analytical Biochemistry, 1987-08-01)A colorimetric reagent, 4-(4'-nitro-2'-methylsulfonylphenylazo)phenyl phosphate (NMPP), has been shown to be an effective substrate of alkaline phosphatase. NMPP and p-nitrophenyl phosphate were applied in comparative ... -
Molecular genetic analysis of tumors in von recklinghausen neurofibromatosis: Loss of heterozygosity for chromosome 17
(Wiley: Genes, Chromosomes and Cancer, 1989-09)The most common inherited syndrome in man predisposing to neoplasia is neurofibromatosis-1 (von Recklinghausen disease) (NF1). We investigated the hypothesis that affected individuals carry a single inactive allele at the ... -
Two identical active X chromosomes in human mammary carcinoma cells
(Elsevier: Cancer Genetics and Cytogenetics, 1990-06)Chromosome G-banding analysis of two human mammary carcinoma cell lines, Elco and MCF-7, showed the existence of two X chromosomes in both cell lines. To determine the state of activity of the X chromosomes, a methylatio ... -
Regulation of liver microsomal inorganic pyrophosphate-glucose phosphotransferase, glucose-6-phosphatase and inorganic pyrophosphatase
(Elsevier: Biochimica et Biophysica Acta, 1967-10-09)Levels of liver inorganic pyrophosphate-glucose phosphotransferase, acid inorganic pyrophosphatase, and glucose-6-phosphate phosphohydrolase (EC 3.1.3.9) have been assayed in normal, alloxan-diabetic, adrenalectomized and ... -
Spectroscopic and interfacial properties of myoglobin/surfactant complexes
(Biophysical Society: Biophysical Journal, 2004-08)The complexes of horse myoglobin (Mb) with the anionic surfactant sodium dodecyl sulfate (SDS), and with the cationic surfactants cetyltrimethylammonium chloride (CTAC) and decyltrimethylammonium bromide (DeTAB), have been ... -
Specification of first quartet micromeres in Ilyanassa involves inherited factors and position with respect to the inducing D macromere.
(Company of Biologists: Development, 1998-10-15)In the embryos of the gastropod Ilyanassa obsoleta, the development of several ectodermal structures requires an inductive interaction between the micromeres and the D macromere. The first quartet micromeres (1a, 1b, 1c ... -
Micromere specification in Ilyanassa obsolete involves both cytoplasmic inheritance and cell position relative to the inducing D macromere.
(Elsevier: Developmental Biology, 1995-08)By virtue of its inheritance of polar lobe material, the D macromere signals the overlying micromeres to develop specialized ectodermal structures (Clement, A., J Exp Zool. 149:193). The first quartet micromeres 1a, 1b, ... -
Liver aldolase anomeric specificity
(American Chemical Society: Biochemistry, 1980-06-10)Stopped-flow kinetic studies of liver aldolase and of mixed liver-muscle aldolase catalyzed reactions of fructose 1,6-bisphosphate (FBP) have been carried out and interpreted by computer simulation. These experiments ... -
Isomerization of the predicted beta-D-fructose 6-phosphate
(Elsevier: Archives of Biochemistry and Biophysics, 1978-07)Phosphomannose isomerase (D-mannose 6-phosphate ketol-isomerase) (EC 5.3.1.8) has been shown to use the predicted beta-D-fructose 6-phosphate as substrate. The fate of alpha-D-fructose 6-phosphate is not determined by these ... -
Inhibition and inactivation of liver aldolase
(Elsevier: Archives of Biochemistry and Biophysics, 1981-02)Substrate analogs xylulose 1,5-bisphosphate, glucitol 1,6-bisphosphate, alpha-2,5-anhydroglucitol 1,6-bisphosphate, alpha-, beta-methyl fructofuranoside 1,6-bisphosphate, ribulose 1,5-bisphosphate, ribulose 5-phosphate, ... -
RNA processing and clinical variability in neurofibromatosis type I (NF1)
(Oxford University Press: Human Molecular Genetics, 1997-09-01)Neurofibromatosis type 1 (NF1) is a common genetic disorder which predisposes affected individuals to a variety of clinical features including tumors of the central and peripheral nervous systems. The product of the NF1 ... -
NF1 mRNA isoform expression in PC12 cells: modulation by extrinsic factors
(Elsevier: Experimental Cell Research, 1996-10)The rat neurofibromatosis type I (NF1) gene expresses several transcript isoforms which differ by the alternative splicing of exons 23a and 23b in the region encoding the GTPase-activating protein-related domain. The ... -

Viral oncoprotein binding to PRB, P107, P130, AND P300
(Elsevier: Virus Research, 1995-02)The purpose of this review is to bring attention to some additional work in the tumor virus/tumor suppressor field which may have been overshadowed by reports describing adenovirus, SV40, and HPV oncoprotein binding to pRB ... -
Transposition of the oncogene ets-1 in t(11;19) translocation in acute leukemia
(Elsevier: Cancer Genetics and Cytogenetics, 1990-12)The specific chromosomal rearrangement t(11;19)(q23;p13) has been identified as a nonrandom chromosomal rearrangement in acute leukemia. The breakpoint, 11q23, coincides with the ets-1 oncogene locus. However, only very ... -
Leech-Repellent Property of Eastern Red-Spotted Newts, Notophthalmus viridescens
(American Association for the Advancement of Science: Science, 1971-12-10)Eastern red-spotted newts (Notophthalmus viridescens, Salamandridae) are rarely attacked by leeches. This protection is not shared by related salamandrids or by Ambystoma (Ambystomatidae). Tetrodotoxin is not the repelent. ... -
Metabolic correlates of the foraging and social behaviour of dart-poison frogs
