Inclusion body refolding protocol
WebHowever, HPH can be a critical unit operation influencing inclusion body (IB) quality and, subsequently, refolding yields. Here, a protocol for homogenization and IB washing is presented in combination with analytical methods suitable to evaluate these unit operations. WebThe process of recovering bioactive proteins from IBs consists of solubilization of IB aggregates using denaturants, followed by refolding of the solubilized protein. Here, we …
