I would like to add that in my experience the pellets for these huge constructs never usually dissolves completely, as observed in my minis and these midis, but whatever dissolves is enough to give me positive results with the minis. Our Qiagen midi kits are new as we go through them very quickly. The results do not change if I repeat diagnostics with a smaller volume of DNA. First, when I do a restriction diagnostic on the midi prep, all I get is either a smear or a very bright spot on the gel. However, after the midi prep, I am getting nothing at all. Sample it: Select the Clone Stamp tool and hold the Option key (on Mac) or the Alt key (on Windows) to bring up the crosshairs. Here, a protocol using TOPO TA cloning kit (Invitrogen) is shown. Usually, this is done for the PCR-amplified DNA after round 7 or later selection rounds, depending on the enrichment of the binders. After diagnostics I proceed to a midi prep with the culture solutions that gave me positive clones following mini preps. Open it: Open the image you want to work with. After PCR using Taq polymerase, the fragments are cloned into plasmids by TA cloning (Taq amplified) for sequencing. 2ml culture solutions and put them back into the shaker. You can quickly see how fast you can type and compare your result with your friends. Simultaneously, I add 2ml of LB to the remainder.

To be extra vigilant, what I have been doing is pick colonies for mini preps and using 1.8ml of the 2ml bacterial culture for each colony to do the minis, followed by a restriction digest diagnostic. With rapid development of the technology, including tremendous improvement of throughput, accuracy, automation, and commercialization, scRNA-seq techniques have been widely applied to address critical biological and medical questions. I have successfully obtained these from mini preps but when I turn to midi preps, I just get a smear (when visualized on gel). This starts from the first single cell RNA-seq (scRNA-seq) technique developed in 2009 1. I've been working with some very large constructs which I've obtained via the multi-gateway cloning technique.
