Molecular Marker to Identify Two Stingless Bee Species: Tetragonisca angustula and Tetragonisca fiebrigi (Hymenoptera, Meliponinae)

open access: yesSociobiology, 2014
Tetragonisca angustula and T. fiebrigi esterases were biochemically characterized by their inhibition pattern and thermostability. Workers of both species were collected from nests at the State University of Maringa. In T.

Low level of isoenzyme variation in an island population of Juniperus oxycedrus subsp. macrocarpa (sm. ex sibth.) ball

open access: yesActa Societatis Botanicorum Poloniae, 2014
The isoenzyme variation in a geographically well isolated population of Juniperus oxycedrus subsp. macrocarpa from Korfu island was investigated. Based on the 18 putative isoenzyme loci a very low level of variation has been observed.

Isoenzyme analysis of Arthrobotrys, a nematode-trapping fungus

open access: yesBrazilian Journal of Medical and Biological Research, 1997
Extraction and isoenzyme analysis of four isolates of Arthrobotrys including A. musiformis, A. robusta and A. conoides were conducted. Among the 14 enzymes studied by starch gel electrophoresis, using morpholine-citrate as gel/electrode buffer, the ...

Total tissue lactate dehydrogenase activity in endometrial carcinoma [PDF]

open access: yes, 2008
Lactate dehydrogenase (LDH) is essential for continuous glycolysis necessary for accelerated tumor growth. The aim of this study was to reconsider if assay of total tissue activity of this enzyme could be useful as marker for endometrial carcinoma (EC ...

Isoenzyme polymorphism of almond genotypes selected in the region of northern Serbia

open access: yesHorticultural Science, 2010
Isoenzyme polymorphism was studied in 20 almond (Prunus dulcis [Mill.] D.A. Webb) genotypes selected from seedling populations of unknown almond cultivars in the region of northern Serbia (Vojvodina). Fourteen enzyme systems were studied using the method

Radioimmunoassay of creatine kinase isoenzymes in human serum: isoenzyme MM.

open access: yesClinical Chemistry, 1978
Abstract Measurement of the mass concentration of serum enzymes by radioimmunoassay provides direct quantitation of specific isoenzymes and may be less subject to some of the limitations of traditional assay procedures for enzymes. We describe the development of a sensitive and specific radioimmunoassay for the muscle isoenzyme of ...

Pancreatic phospholipase A2 activity in acute pancreatitis: A prognostic marker for early identification of patients at risk [PDF]

open access: yes, 2002
Remarkably elevated levels of phospholipase A(2) (PLA(2)) are measurable in human blood samples in cases of acute pancreatitis. The source of the enzyme was first thought to be exclusively the pancreas, but now it is generally accepted that two ...
