Rapid method for preparing cell-free extracts of Aspergillus ochraceus.
A rapid method for preparing cell-free extracts of Aspergillus ochraceus was developed. Mycelial mats were prefrozen in liquid nitrogen, ground to a fine powder in a cold mortar, and homogenized in an all-glass mechanical homogenizer. This method provided preparations averaging 43.0 mg of protein per g of mycelium (wet weight). The method was fast, efficient, and did not subject the extract ...
متن کاملThe Action of Rennin on Casein
In order to determine if the change from casein to paracasein results in the cleavage of any of the elements contained in the casein molecule, it is imperative that pure casein be used as a standard of comparison, and that the rennin activity be positively differentiated from any further proteolyt,ic activity of the enzyme under consideration; for it is quite evident that “Rennin action is prob...
متن کاملchemical recycling of polycarbonate waste using conventional heating and microwave assisted method
پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...
Development of a Method for Pb Functionalization and Preparing Immunogenic Complex
Antibody based methods have numerous advantages compared to other detection methods. However, heavy metals cannot stimulate the immune antibody response; it is the main obstacle for preparation of the antibodies that used in detection methods of the metals. The production of the immunogenic Pb complexes by using cost benefit linkers of EDTA and DTPA were investigated in this study.BS...
متن کاملA Simple and Rapid Method for Preparing a Cell-Free Bacterial Lysate for Protein Synthesis
Cell-free protein synthesis (CFPS) systems are important laboratory tools that are used for various synthetic biology applications. Here, we present a simple and inexpensive laboratory-scale method for preparing a CFPS system from E. coli. The procedure uses basic lab equipment, a minimal set of reagents, and requires less than one hour to process the bacterial cell mass into a functional S30-T...
