WebThe coding region for the sortase A (SrtA) of Staphylococcus aureus was fused at the N-terminus of LfcinB. The SrtA-LfcinB fusion protein in E. coli C43(DE3) was expressed with the expected sizes of 21 kDa and 38 kDa by pET21b-SrtA-LfcinB and pET32-1SrtA-LfcinB constructs, respectively. Increased levels of the TrxA-His-SrtA-SrtA-LfcinB fusion protein … WebSonicate 4-6 cycles (10x10sec pulses with 20 seconds between each 10 sec pulse = 1 cycle at 50% power) in an ice + water bath with a 2 minute cooling period in between each cycle. CRITICAL STEP: In this step you can thermally denature your protein and compromise your sample, if not paying attention. Web2. Dilute the bacterial culture 1:100 into 2xYT medium and grow till OD600=0.6. Induce (with IPTG: 0.4 and 0.8mM). Grow for various time periods (5hrs, ON). Harvest cells by centrifugation (6000 rpm/5min), aspirate supernatant and freeze pellet at -70oC. 3. Resuspend 1.5 ml pellet of bacterial cell culture in 0.75 ml of lysis buffer (see below). robot lawn mower vine
