Filtered crude peptides were precipitated in ice cold tertiary butyl ether, and separated by centrifugation at 2000×g for 10 min (2 3 cycles of ether-precipitation and centrifugation were used to minimize cleavage-deprotection byproducts).
To minimize proteolytic cleavage of the desired recombinant protein, a cocktail of protease inhibitors was also added (2.0 mg/mL aprotinin, 0.5 mg/mL leupeptin, 1.0 mg/mL pepstatin A, and 2 μL/mL crude lysate of Pefabloc SC).
The recovered transcripts were dissolved in 1× RNAi buffer (30 mM HEPES pH 7.4, 100 mM KCl, 5 μM MgCl2, 0.5 μM DTT, 10 (v/v) % glycerol) and annealed to end-matching LNA oligos (1 μM) (to minimize exonucleolytic cleavage upon incubation with cell extracts) by 30 s incubation at 95°C followed by cooling to room temperature.
Avoid bras without an underwire, since these offer less lift and will minimize your cleavage.
Unless you're applying for a job where your looks are obviously an important factor, minimize the cleavage as much as possible.
Adhesively bonded joints are designed to maximize tensile and compressive stresses, and to minimize peel and cleavage stresses, so the magnitude of the former two are generally much larger than the latter two.
The use of a higher-fidelity nuclease domain might be particularly appropriate for applications such as gene therapy where minimizing off-target cleavage is paramount.
One concern with closed vitrification carriers is whether the rate of cooling is sufficient to minimize cell damage in both cleavage and blastocyst stage embryos.
Three steps, antibody purification, enzymatic activity, and mass spectrometric detection of specific cleavage products, combine to minimize cross reactivity.
This method utilizes inclusion bodies-directed expression and cheap chemical cleavage with cyanogen bromide in order to minimize the cost of the procedure compared to the use of less efficient proteolytic enzymes.
