Isolation and Characterization of Bovine Lymphocyte Nuclear Matrix

Small nuclear RNA-protein complex anchors on the actin filaments in bovine lymphocyte nuclear matrix.

When the nuclear matrix from bovine lymphocytes was digested by RNase-depleted trypsin, the bulk of the matrix proteins, except actin, were hydrolyzed. The digestion left rapidly sedimented spherical structures (trypsin-treated nuclear matrix), which mainly were composed of actin (Nakayasu, H. and K. Ueda. Exp. Cell Res. 143, 55-62, 1983). Almost all the small nuclear RNAs of the original nucle...

Isolation and characterization of a bovine herpesvirus 3 From cases of calf pneumonia in Iran

Isolation and characterization of bovine parathyroid hormone.

It has been known for some time that many active principles found in tissues are difficult to extract and purify, not only because of problems of stability, but also because they often apljear to bc bound, in some more or less specific way, with other tissue components. Strong dissociating solvents may be required to achieve disentanglement from other components, but such solvents must not caus...

synthesis and characterization of some macrocyclic schiff bases

ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
