Calibration methods and avoidance of errors in measurement of intracellular pH (pHcyt) using the indicator bis(carboxyethyl)-5(6)-carboxyfluorescein (BCECF) in human platelets.

Journal of fluorescence

Valant PA, Haynes DH.
PMID: 24241630
J Fluoresc. 1992 Sep;2(3):191-206. doi: 10.1007/BF00866934.

Determinations of pHcyt in suspensions of human platelets using BCECF [bis(carboxyethyl)-5(6)-carboxyfluorescein] can be seriously biased by leakage of the fluorescent indicator. Two methods ("pH jump" and "Mn(2+)") are presented for determining the fraction of external indicator (B ext) and...

Planta. 1978 Jan;143(3):315-22. doi: 10.1007/BF00392004.

Photosystem II (PS II) reactions of chloroplast particles show the same variations during the synchronous life cycle of Scenedesmus obliquus, strain D3 (Gaffron Biol. Zbl. 59, 302 1939), as the whole cells they derived from. Photosystem I (PS I)...

BACKGROUND: Mitochondrial diseases belong to the most severe inherited metabolic disorders affecting pediatric population. Despite detailed knowledge of mtDNA mutations and progress in identification of affected nuclear genes, diagnostics of a substantial part of mitochondrial diseases relies on clinical...

[beta]-Glucan Synthesis in the Cotton Fiber (I. Identification of [beta]-1,4- and [beta]-1,3-Glucans Synthesized in Vitro).

Plant physiology

Okuda K, Li L, Kudlicka K, Kuga S, Brown RM.
PMID: 12231764
Plant Physiol. 1993 Apr;101(4):1131-1142. doi: 10.1104/pp.101.4.1131.

In vitro [beta]-glucan products were synthesized by digitonin-solubilized enzyme preparations from plasma membrane-enriched fractions of cotton (Gossypium hirsutum) fiber cells. The reaction mixture favoring [beta]-1,4-glucan synthesis included the following effectors: Mg2+, Ca2+, cellobiose, cyclic-3[prime]:5[prime]-GMP, and digitonin. The ethanol insoluble...

Rapid Enrichment of CHAPS-Solubilized UDP-Glucose: (1,3)-beta-Glucan (Callose) Synthase from Beta vulgaris L. by Product Entrapment : Entrapment Mechanisms and Polypeptide Characterization.

Plant Physiol. 1991 Oct;97(2):684-92. doi: 10.1104/pp.97.2.684.

Rapid enrichment of CHAPS-solubilized UDP-glucose:(1,3)-beta-glucan (callose) synthase from storage tissue of red beet (Beta vulgaris L.) is obtained when the preparation is incubated with an enzyme assay mixture, then centrifuged and the enzyme released from the callose pellet with...

Synthesis of Fibrils in Vitro by a Solubilized Cellulose Synthase from Acetobacter xylinum.

Science (New York, N.Y.)

Lin FC, Brown RM, Cooper JB, Delmer DP.
PMID: 17791798
Science. 1985 Nov 15;230(4727):822-5. doi: 10.1126/science.230.4727.822.

A digitonin-solubilized cellulose synthase was prepared from Acetobacter xylinum. When this enzyme was incubated under conditions known to lead to active synthesis of 1,4-beta-D-glucan polymer (cellulose), electron microscopy revealed that clusters of fibrils were assembled within minutes. Individual fibrils...

Cellular Fractionation of Chlamydomonas reinhardii with Emphasis on the Isolation of the Chloroplast.

Plant physiology

Klein U, Chen C, Gibbs M, Platt-Aloia KA.
PMID: 16663028
Plant Physiol. 1983 Jun;72(2):481-7. doi: 10.1104/pp.72.2.481.

A method for cellular fractionation of Chlamydomonas reinhardii, SAG 11-32/b, and isolation of intact chloroplasts from synchronized cells of the alga is described. The procedure for cell fractionation comprises essentially four steps: (1) protoplast production with autolysine; (2) lysis...

Photosynthetic Reactions by Lysed Protoplasts and Particle Preparations from the Blue-Green Alga, Phormidium luridum.

Reactions of photosynthetic electron transport and photophosphorylation were studied in preparations from the blue-green alga, Phormidium luridum. Osmotic lysis of protoplasts proved to be a superior technique for the production of cell-free preparations with high enzymatic activity. Such lysed...

Biosynthesis of Insoluble Glucans From Uridine-Diphosphate-d-Glucose With Enzyme Preparations From Phaseolus aureus and Lupinus albus.

Plant Physiol. 1968 Oct;43(10):1703-9. doi: 10.1104/pp.43.10.1703.

Particulate, and digitonin-solubilized, enzyme systems from Phaseolus aureus and Lupinus albus catalyze the biosynthesis of aqueous-insoluble glucans from UDP-d-glucose. The digitonin treatment greatly increases the enzymic activity of (per unit protein) both the 34,000g pellet and the supernatant liquid...
