The effect of culture system and protein supplementation on the development of one-cell porcine embryos was investigated. One hundred and sixty-four one-cell embryos were collected at slaughter from 19 handmated gifts. Culture systems evaluated were microdrops of Whitten's medium (WM) under paraffin oil (M) or tubes with 4.0 ml of WM (T). Also tested was T with a 2.0 ml paraffin oil overlay (O)...

Proteins that have been modified by long-term exposure to glucose accumulate advanced glycosylation end products (AGE) as a function of protein age. In these studies, we have characterized the interaction of AGE-protein with mouse peritoneal macrophages, using AGE-modified bovine serum albumin (AGE-BSA, prepared by incubation with glucose) as a probe. AGE-BSA was specifically bound to cells at ...

Herein, 1F2, an anti-HER2 monoclonal antibody (mAb), was covalently coupled to the surface of 5-Fluorouracil (5-FU) loaded bovine serum albumin (BSA) nanoparticles. Concerning two different crosslinkers for conjugation of 1F2, Maleimide-poly (ethylene glycol)-Succinimidyl carbonate (Mal-PEG5000-NHS) was selected due to its higher conjugation efficiency (23±4 %) obtained in comparison to N-succi...

Background: Coumarins comprise a large family of heterocyclic compounds with benzo-a-pyrone moiety. Objectives: This study aimed to analyze the binding affinity 3-(1H-tetrazol-5-yl) coumarin bovine serum albumin (BSA) and calf thymus DNA (Ct-DNA) using fluorescence spectroscopy. The quenching was recognized during interaction between BSA, followed by static mechanism. Methods: hydrogen bonds, h...

Human 5-HT7A receptors positively modulated adenylyl cyclases via Gs subtypes of G proteins in human embryonic kidney 293 cells, and bound 5-hydroxytryptamine (HT) with high and low affinity (K(I) values of 1.5 +/- 0.3 and 93 +/- 4 nM). More than 60% of 5-HT7A receptors, however, displayed the high-affinity 5-HT binding with no sensitivity to 5'-guanylylimidodiphosphate. In this study, we found...

The effect of arsenic on the binding metronidazole (an anti-amoebic agent) to bovine serum albumin (BSA) was studied by equilibrium dialysis (ED) method in order justify nature capability drug and BSA. There decrease concentration due addition arsenic. But free increased with increasing when only BSA present. result obtained no added 41% whereas this release 7% an from 0.5x10-5 10x10-5M. 36% 71...
