Trypsin should be stored at very cold temperatures (between −20 and −80 °C) to prevent autolysis, which may also be impeded by storage of trypsin at pH 3 or by using trypsin modified by reductive methylation.
As tripsinas deberían almacenarse a temperaturas moi frías (entre −20 °C e −80 °C) para impedir a autólise, a cal pode impedirse tamén almacenándoas a pH 3 ou usando tripsina modificada por metilación redutiva.
