Purified plasmids in 96-well microtiter plates were quantified with a PowerWave XS spectrometer (Bio-Tek) and normalized to a final concentration of 40 ng/µL with a TheOnyx (MWG Biotech) liquid-handling robot. doi: 10.1074/jbc.m201187200 View Article PubMed/NCBI Google Scholar 15.

Primer lengths of 20 - 40 nucleotides usually produce acceptable results.Table 1 outlines the average number of nucleotide substitutions per template as a function of the number of EP-PCR doublings and Cells were detected using Object Segmentation (kernel size  = 57, Sensitivity  = 55), followed by Fill Holes and Sieve (Binary) based on size (>10 µm2). van Diepen, Affiliation Respiratory Disease Area, Novartis Institutes for Biomedical Research, Horsham, United Kingdom ⨯ Anthony Marelli, Affiliation Infectious Diseases, Genomics Institute of the Novartis Research Foundation, San Diego, California, United Rasila TS, Pajunen MI, Savilahti H (2009) Critical evaluation of random mutagenesis by error-prone polymerase chain reaction protocols, Escherichia coli mutator strain, and hydroxylamine treatment.

Recent studies have revealed a cardioprotective role of the IP receptor and hIP receptor dysfunction has been implicated in numerous cardiovascular abnormalities, including myocardial infarction, hypertension, thrombosis and atherosclerosis [4]–[9]. Mean and Sum of the fluorescence detected was taken for each well as an estimate of the relative expression levels for each mutant receptor. Furthermore, genetic variants in the hIP receptor resulting in deficits of hIP receptor function have been correlated with increased disease severity in patients with coronary artery disease [10], [11].

Briefly, 500–1000 ng of plasmid DNA (pcDNA5-HA-hPTGIR) was mutagenized by PCR according to the manufacturer's protocol using the following primers: IPR-for: 5′- CGACTCACTATAGGGAGACCCAAGCTGG -3′, IPR-rev: 5′- CAACTAGAAGGCACAGTCGAGGCTGATC -3′. Estimated distribution of amino acid (AA) changes relative to the mutation rate (library size: 4000 plasmids).

The functional characterization of our library of >4000 mutants of the hIP receptor generated by epPCR identified 18 mutants of the hIP receptor with partial or complete loss of receptor activity Here we set out to investigate the applicability of high throughput random mutagenesis to study the structure-function relationship of hIP receptor.

Cell culture and transfection HEK293 GloSensor-20F cAMP cells (Promega) were maintained in DMEM supplemented with foetal bovine serum (10% v/v) and hygromycin (200 µg/mL) at 37°C, 5% CO2. Mutagenised plasmids were then isolated and washed at least 3 times using the QiaQuick PCR purification kit (Qiagen), and finally eluted with 50 µL EB buffer from the kit and diluted PCR products were separated by gel electrophoresis and purified using a gel-extraction kit (Qiagen).

Of these 34 mutants, 18 were expressed at the cell surface and demonstrated full or partial loss of receptor function. ISBN 3-900051-07-0, URL; [13]).
