Figure 1. Comparison of SDS–PAGE gel patterns of proteins in camel tear fluids between summer and winter. A: Proteins of camel tears in the summer (lane Cs) and in the winter (lane Cw) were separated on a 13% gel with equal amount of total tear proteins in each sample. Thirteen well resolved bands are detected in both lanes. B: Graphic of lane comparison of camel tear proteins between the summer (dotted line) and the winter (solid line). B1, Band1; B2, Band2; B3, Band3; and so forth in B are correspondent with those in A.
