Alkaline phosphatase electrophoretic patterns characteristic of three phases in early human trophoblast development are described in this preliminary communication. Phase 1 (6 to 10 weeks) consists entirely of two heat-sensitive, L-homoarginine-inhibited bands, the slower one of which possesses antigenic determinants of live-bone-type alkaline phosphatase, whereas the fast band lacks any of the...

104 samples from 27 accessions belonging to 12 species of genus Epimedium were studied on the basis of cytology observation, POD (i.e., peroxide) isozyme, high performance liquid chromatography (i.e., HPLC) fingerprint, and interspecific hybridization. The cytology observation showed karyotypes of twelve species studied; all are 2A symmetry type of Stebbins standard and similar to each other, a...

The sagittal organization of the mammalian cerebellum can be observed at the anatomical, physiological and biochemical level. Previous screening of monoclonal antibodies produced in our laboratory has identified two intracellular antigens, zebrin I and II, that occur exclusively in adult cerebellar Purkinje cells. As their name suggests, the zebrin antibody staining of the Purkinje cell populat...

Isoelectrofocusing studies of mouse tissue extracts show mice to have a pyruvate kinase isozyme pattern very similar to that of the rat. Moreover, electrofocusing or kinetic assays conducted on liver extracts from normal mice and from mice bearing Ehrlich ascites tumors show that the latter have a higher proportion of the fetal K-isozyme of pyruvate kinase. Serial injection of the supernatant r...

Growth rate, histolÃ3gica! course, and polymorphic enzyme pattern (glucose 6-phosphate dehydrogenase, glucose phos phate isomerase, and phosphofructokinase) were studied in eight childhood tumors xenotransplanted serially to nude mice. The growth rate of these tumors (three nephroblastomas, one hyper calcémierenal tumor, three rhabdomyosarcomas, and one malig nant histiocytosis) appeared stabl...

the present study was aimed at the development of a somoclonal variant and isozyme marker for phyllanthus amarus schum & thonn using inter-nodal segments and the enzyme peroxidase. maximum callus proliferation was obtained on murashige and skoog’s medium supplemented (ms) with 1.0 mg/l of 2,4-dichlorophenoxyacetic acid. three weeks-old pale yellowish white semi-friable callus was used for o...

background: withania somnifera l. dunal, (ashwagandha) belongs to the family solanaceae and is known as ‘indian ginseng’ in the traditional system of medicine. objectives: in the present investigation, comparative analysis was carried out between two different ecotypes of w. somnifera related to total soluble protein and antioxidant enzyme activity [catalase (cat), superoxide dismutase (sod) an...

In the present study six different populations of L. orbonalis were collected and subjected to analysis of genetic variability in terms of carboxylesterase isozyme pattern and DNA polymorphism using RAPD-PCR. Pattern of carboxylesterase revealed a similar isozyme cluster in the populations namely, sivaganga (population-3), dindigal (population-4), virudhunagar (population-5) and coimbatore (pop...
