Biosynthesis and identification of enzymes of the cellulase system of Trichoderma reesei
… of amino acid composition carbohydrate content, electrophoretic mobility and ultraviolet spectrum. Similar data for the other cellobiohydrolase suggest that it represents an enzyme not previously identified. An endoglucanase was also isolated which, on the basis of its amino acid composition and …

Betaine-Homocysteine Methyltransferase: Tissue Distribution, Nutrient Regulation, Genomic Organization, and Promoter Isolation
The electrophoretic mobility (45 kDa) and the nucleotide sequence of the human kidney BHMT has been shown to be identical to liver BHMT. Initial rate data was plotted according to the method of Hanes and the Michaelis Constants were estimated to be 2160 muM and <10 muM for betaine and …

An electrophoretic method for the isolation of isohistones from the embryo of the sea urchin Parechinus Angulosus
… chromosomal proteins characterized only by their electrophoretic mobility as histone variants, and secondly the creation of a micropreparative electrophoretic method. These are the prerequisites for later investigations into the specific roles of histones in the process of differentiation.

Using Covalent and Non-Covalent Chemistry to Control Properties of Single -Walled Carbon Nanotubes
Electrophoretic mobility control is demonstrated via covalent functionalization with 4-hydroxybenzene diazonium and non-covalent functionalization with sodium cholate surfactant. Solution-phase solubility without surfactants can be achieved using high levels of covalent functionalization with aryl …

Controlling the interfacial behaviour of colloidal microgel systems
… Key properties of the microgels, i.e. size, electrophoretic mobility and volume phase transition temperature (VPTT), were determined by dynamic light scattering (DLS), laser Doppler electrophoresis, UV-visible spectrophotometry and scanning electron microscopy. The influence of co-monomer …

The relationship between two species of fur seals Arctocephalus Tropicalis (Gray) and A. Gazella (Peters) on Marion Island
… measurements. The two species differed in the electrophoretic mobility of the serum protein, transferrin. The extent of hybridization appears to be limited with the hybrids representing 0,1% of the total fur seal population (34528 A. tropical is and 300-400 A. gazella). Although the seasonal …

A molecular genetic investigation of rhabdomyosarcoma
… recognition sequences for the protein trartslin. Electrophoretic mobility shift studies (EMSA) confirm that these sequences bind translin. These findings suggest that translin may not only be important in the genesis of chromosomal trartslocations in lymphoid malignancy, but also in translocations …

CAPILLARY ELECTROPHORESIS ANALYSIS OF SINGLE-STRANDED DNA APTAMERS AND THEIR INTERACTIONS WITH PROTEIN TARGETS AND CARBON DOTS
… carbon dots (CDs) could significantly change the mobility of ssDNA samples upon noncovalent interaction. Preliminary observations revealed substantial interactions between carbon dots and ssDNA, as evidenced by changes in fluorescence emission of labeled DNA samples, but further studies are needed …

TCF4-mediated Transcriptional Regulation of Krüppel-like Factor 4 Gene
… 개의 conserved 지역에 TCF4 단백질이 binding 하는지 알아보기 위해, electrophoretic mobility shift assay를 수행하였다. ATCAAAG 지역에는 TCF4 binding complex band가 관찰되었지만 TACAAAG 지역에서는 관찰되지 않았다. 이 결과는 TCF4 단백질이 KLF4 promoter 지역의 먼 곳에서 조절할 것이라는 사실을 보여준다. 위의 결과들로 미루어볼 때 TCF4 단백질이 KLF4 유전자에 대한 전사 과정을 조절하는데 있어 중요한 역할을 할 것이라 여겨진다.
