Real-time PCR-based method for assaying the purity of bacterial artificial chromosome preparations.
Large-scale genomic sequencing projects (such as that being undertaken for the human genome project) often prepare large insert (100–200 kb) libraries in bacterial artificial chromosome (BAC) vectors. Short insert libraries are then constructed from individual isolated BACs, and clones from the short insert libraries are randomly selected for sequencing to the requisite coverage. BAC DNA is fir...

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...
The Strophanthins of Strophanthus Eminii
In accordance with a plan to investigate as fully as possible the essential chemistry of the strophanthins and other cardiac glucosides, we have attempted to include for comparative purposes, as opportunity presented itself, a study of the digitaloid glucosides and aglucones which occur in the different species of Strophanthus plants. Our own and previous investigations have had to do principal...
متن کاملA broth dilution method of assaying streptothricin and streptomycin.
The agar dilution (Waksman, 1943) and the agar diffusion (Foster and Woodruff, 1943b) methods of assay of streptothricin and streptomycin are the procedures most commonly employed and have led to what Waksman calls "dilution units" (Waksman, 1943) and "diffusion units" (Schatz, Bugie, and Waksman, 1944). However, in addition, Waksman speaks of "Escherichia coli units," or "Bacillus subtilis uni...
