“…However, there are also articles in the literature that indicate that protein folding occurs during incubation at lower pressure levels (0.3-0.7 kbar) [13,27] or at atmospheric pressure [9]. To determine the conditions that favor TsnC refolding, IB suspensions were subjected to incubation at 2.4 kbar for 16 h. As alternative conditions, the IB suspensions were compressed at 2.4 kbar for 90 min for dissociation of the aggregates, which was followed by decompression to 0.8, 0.4, 0.2 kbar or 1 bar for refolding, condition that was maintained for 16 h before complete decompression and dialysis.…”

“…Therefore, the use of 2-3 kbar constitutes a non-denaturing technique that solubilizes aggregates and keeps the secondary and tertiary protein structure intact, being potentially applicable in protein refolding [9,10]. In this context, HHP has become a technique to obtain high-yield protein refolding [11][12][13][14]. Quantification of the target protein in the soluble fraction often aids determination of the refolding process efficiency [15,16].…”

“…The refolding of oligomers present the additional drawback that is the necessity of high protein concentration, a condition that potentially induce the association of misfolded monomers and that can favor reaggregation instead of the proper association of the monomers. HHP was previously described to be a useful tool for solubilization of aggregated proteins, enabling for the refolding of monomeric (Chura-Chambi et al, 2008Fraga et al, 2010;Malavasi et al, 2011) and oligomeric proteins (Foguel et al, 1999).…”

“…A técnica tem se mostrado eficiente para a renaturação de diversas proteínas (FRAGA et al, 2010;MALAVASI et al, 2011;ZHENG et al, 2013;RODRIGUES et al, 2014;LEMKE et al, 2015) e, portanto, ela foi empregada na tentativa de renaturar as porções da proteína LepA388. Após diferentes condições para a renaturação, o tratamento com o tampão composto por 50 mM Tris-EDTA pH 8,0 e 500 mM de L-arginina pH 11,0 foi o mais eficiente para que a maior concentração das proteínas estivesse na fração solúvel (Figura 33 e Figura A6 da seção Apêndices).…”
