Directed evolution of streptavidin variants using in vitro compartmentalization.
We have developed and implemented an in vitro compartmentalization (IVC) selection scheme for the identification of streptavidin (SA) variants with altered specificities for the biotin analog desthiobiotin. Wild-type SA and selected variants bind desthiobiotin with similar affinities (approximately 10(-13) M), but the variants have off rates almost 50 times slower and a half-life for dissociati...
متن کاملDirected evolution of a thermostable esterase.
We have used in vitro evolution to probe the relationship between stability and activity in a mesophilic esterase. Previous studies of these properties in homologous enzymes evolved for function at different temperatures have suggested that stability at high temperatures is incompatible with high catalytic activity at low temperatures through mutually exclusive demands on enzyme flexibility. Si...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

immunohistochemical expression of p53 and ki-67 in different histopathological variants of basal cell carcinoma
background : basal cell carcinoma is the most common form of skin cancer in men. increased marker expressions of apoptosis and cell proliferation have been found in the majority of basal cell carcinomas. our purpose was to determine whether any correlation between immunohistochemical expressions of p53 and ki-67 in different histopathological variants of basal cell carcinoma and patient’s age, ...
