Naoh protein extraction
Did you know?
WitrynaAlthough NaOH creates an alkali condition that improves protein solubility and yield, NaOH is a strong alkali and also causes degradation [ 34 ]. Therefore, a mild alkaline application with less severity is needed. NH 4 OH is a weak base that creates a mild alkali processing condition, which could potentially reduce protein denaturation [ 35 ]. Witryna28 paź 2024 · The protein extraction of soluble proteins under an alkaline environment was performed according to the method described by Azagoh et al. [ 13 ], with minor modifications. Briefly, 20 g of the DF was mixed with 300 mL of distilled water (1:15 w/v) under magnetic stirring.

WitrynaI'm trying to stabilize my protein by use of different buffers. It obviously loves alkaline pH, because below pH 6 the activity was gone in few days even when stored at -80°C. However, even at pH... WitrynaResults: Protein was extracted from black bullhead catfish (Ameiurus melas) using a pH-shift method. Protein was solubilized using either sodium hydroxide (NaOH) or calcium hydroxide (Ca (OH) 2 ) and precipitated at pH 5.5 using hydrochloric acid (HCl). Protein solubility was greater when Ca (OH) 2 was used compared to NaOH during …
