Jones RL.
PMID: 24306528
Planta. 1980 Nov;150(1):70-81. doi: 10.1007/BF00385617.

Changes in the level of the endoplasmicreticulum (ER) marker enzyme cytochrome-c reductase (EC 1.6.2.1) were followed with time of imbibition of de-embryonated half-seeds of barley (Hordeum vulgare L.) and the subsequent incubation of their aleurone layers in gibberellic acid...

BACKGROUND: Aflatoxins are the most extensively studied group of mycotoxins produced by molds, especially the Aspergillus group, which are highly toxic to animals and humans.OBJECTIVES: Since immunoassay is a simple and rapid method for the analysis of many toxic...

Synthesis of affinity chromatography resins for the purification of brain glutamate decarboxylase.

Possani LD, Bayón A, Tapia R.
PMID: 24271849
Neurochem Res. 1977 Feb;2(1):51-7. doi: 10.1007/BF00966021.

In the present paper we describe the synthesis of Sepharose-boundN-(5'-phosphopyridoxyl)-amino-oxyacetic acid,N-(5'-phosphopyridoxyl)-canaline, andN-(5'-phosphopyridoxyl)-α,γ-diaminobutyric acid (Seph-DAB-PLP), designed for binding specifically brain glutamate decarboxylase (GAD). The three Sepharose-N-(phosphopyridoxyl)-amino acids were capable of binding GAD from a mouse brain soluble preparation. The enzyme...

Auxin-stimulated ATPase in membrane fractions from pumpkin hypocotyls (Cucurbita maxima L.).

Planta

Scherer GF.
PMID: 24302108
Planta. 1981 May;151(5):434-8. doi: 10.1007/BF00386536.

Membrane fractions from Cucurbita maxima hypocotyls were isolated in a medium which inhibits the action of endogenous phospholipases. After removal of soluble phosphatases by Sepharose 2B-CL column chromatography, an auxin-stimulated ATPase activity was found in membrane fractions from linear...

Changes in non-cellulosic cell-wall polysaccharides during the growth of carrot cells in suspension cultures.

Planta

Asamizu T, Nakano N, Nishi A.
PMID: 24264546
Planta. 1983 Jun;158(2):166-74. doi: 10.1007/BF00397710.

The cell-wall composition of carrot (Daucus carota L.) cells has been studied during their growth in suspension culture. Pectic and hemicellulosic polymers were fractionated according to molecular size by a Sepharose 4B column. Polyuronides in the pectic fraction were...

Production, isolation and partial purification of xylanases from anAspergillus sp.

World journal of microbiology & biotechnology

Khanna P, Sundari SS, Kumar NJ.
PMID: 24414515
World J Microbiol Biotechnol. 1995 Mar;11(2):242-3. doi: 10.1007/BF00704661.

AnAspergillus sp., isolated from a rubbish dump, produced 10.6 IU ml(-1) xylanase activity. Two xylanases were recognized and each was purified to homogeneity by two-stage chromatography on DEAE-and CM-Sepharose. Xylanase I had a pI of 7.2 and anM r...

Anti-tumour components of the culture filtrates from Tricholoma sp.

World journal of microbiology & biotechnology

Liu F, Ooi VE, Chang ST.
PMID: 24414897
World J Microbiol Biotechnol. 1995 Sep;11(5):486-90. doi: 10.1007/BF00286357.

The anti-tumour component (Fraction A) found in the culture filtrates of a local mushroom, Tricholoma sp. (strain STC20-T1), was purified using DEAE-cellulose ion exchange chromatography and Sepharose CL-4B gel filtration. Of its two purified sub-fractions, A-1 and A-2, only...

New source of α-d-galactosidase: Germinating coffee beans.

Food chemistry

Shen W, Jin Z, Xu X, Zhao J, Deng L, Chen H, Yuan C, Li D, Li X.
PMID: 26047286
Food Chem. 2008 Oct 15;110(4):962-6. doi: 10.1016/j.foodchem.2008.03.002. Epub 2008 Mar 08.

Enzyme activities of α-Gal from dormant and germinating coffee beans (Coffea arabica) were studied and compared to develop one new source of α-d-galactosidase (α-Gal). During the germination, enzyme activity showed a continuous improvement: it increased slowly within 25 days...

Isolation, purification and properties of an R-phycocyanin from the phycobilisomes of a marine red macroalga Polysiphonia urceolata.

PloS one

PLoS One. 2014 Jul 03;9(7):e101724. doi: 10.1371/journal.pone.0101724. eCollection 2014.

Phycobilisomes were prepared from a marine red macroalga Polysiphonia urceolata (P. urceolata) by sucrose step-gradient ultracentrifugation. From the prepared phycobilisomes, an R-phycocyanin was isolated by gel filtration on Sephadex G-150 and then purified by ion exchange chromatography on DEAE-Sepharose...
