(a) 12% SDS–PAGE gels. Lanes 1 and 2 correspond to the purified SIP fraction before crystallization and dissolved multiple crystals of the SIP, respectively. Lane L corresponds to the protein ladder (labelled in kDa). (b) UV–visible profile of the purified protein. The UV–visible spectrum was measured in a Shimadzu UV-1800 UV–Vis spectrophotometer using a fast scan rate. |
