The cytosolic aldehyde dehydrogenase (ALDH) isozyme from cyclophosphamide (f PA) resistant 1.1210 cells (L1210/CPA) was purified to apparent homogeneity using ternary enzyme complex-dye ligand chromatography. The purified isozyme migrates as a single band at M, 51,000 in sodium dodecyl sulfate polyacrylamide gel electrophoresis and as a single charge species at isoelectric point = 5.8 in isoele...

In order to characterize fusion products from yeast protoplasts and their segregants, with important features to the wine making industry, electrophoretic karyotyping and RAPD (Random Amplified Polymorphic DNA) were utilized. Electrophoretic karyotyping was performed by the CHEF (“contour-clamped homogeneous electric field electrophoresis”) method, which allowed the detection of chromosomal ban...

Abstract We performed an analysis using isoelectric focusing to comprehensively clarify the isozyme composition of laccase derived from Japanese lacquer tree, Toxicodendron vernicifluum . When water extracts acetone powder obtained were subjected focusing, five bands within pI 7.35–9.30 and nine 3.50–5.25 detected Coomassie staining. Similarly, activity staining guaiacol showed three 3.50–4.25....

The detection of Bence Jones protein, an important part of the investigation of suspected myeloma, is most commonly done by agarose or cellulose nitrate electrophoresis followed by immunofixation. Bence Jones protein is recognized as single or multiple bands of one type of light chain. Unfortunately, improvements in sensitivity of these techniques (use of high-affinity antisera and higher resol...

Thalamocortical afferents in the visual cortex of the adult sable ferret are segregated into eye-specific ocular dominance bands. The development of ocular dominance bands was studied by transneuronal labeling of the visual cortices of ferret kits between the ages of postnatal day 28 (P28) and P81 after intravitreous injections of either tritiated proline or wheat germ agglutinin-horseradish pe...

to investigate the genetic diversity of 21 rapeseeds (brassica napus l.), 20 semi-random isj and ssr primers were used. primers produced a total number of 158 (81.5%) polymorphic bands (51 ssr and 107 isj bands). average numbers of polymorphic bands for isj, ssr and combined of them were 10.7, 5.1 and 7.9, respectively. pic values ranged from 0.0150 for specific primer o110d08 to 0.3420 for sem...

Two flavonoid-deficient mutants, designated as fldL-1 and fldL-2, were isolated in EMS-mutagenized (0.15%, 10 h) M(2) progeny of grass pea (Lathyrus sativus L.). Both the mutants contained total leaf flavonoid content only 20% of their mother varieties. Genetic analysis revealed monogenic recessive inheritance of the trait, controlled by two different nonallelic loci. The two mutants differed s...

Purified preparations of Coxiella burnetii were examined for enzymes of the glycolytic pathway. Glucose-phosphate isomerase, fructose-1,6-diphosphatase, aldolase, glyceraldehyde-3-phosphate dehydrogenase, and pyruvate kinase were shown to be present in C. burnetii extracts. Heat-killed C. burnetii purified with normal yolk sacs demonstrated no activity after disruption. Aldolase was shown to be...

Pulsed-field gel electrophoresis techniques were used to examine the chromosomes of Pneumocystis carinii isolated from laboratory rats and two human subjects. P. carinii organisms isolated from each of four rat colonies and from two patients each produced a distinct band pattern, but in all cases the bands ranged in size from 300 to 700 kilobase pairs. P. carinii from three rat colonies produce...
