An Evaluation of 3-Rhamnosylquercetin, a Glycosylated Form of Quercetin, against the Myotoxic and Edematogenic Effects of sPLA2 from Crotalus durissus terrificus
Figure 1
Purification and chemical modification of secretory phospholipase A2 (sPLA2). A fractionation of the whole venom was performed by reverse-phase HPLC (C5 column, 0.10 cm × 25 cm) using a nonlinear concentration gradient of buffer to obtain a high-purity protein. (a) shows a comparative profile of native sPLA2, sPLA2 : Q, and sPLA2 : Qn when subjected to reverse-phase HPLC. (b) shows the MALDI-TOF mass spectrometry analysis of native sPLA2 and sPLA2 : Qn, indicating the difference in the molecular mass corresponding to one molecule of bound quercitrin.
