Complex formation of WSLP/siRNA. (a) Determination of siRNA in WSPL/siRNA complexes in different weight ratios by using 20% PAGE gel. Lanes 1–8: naked siRNA, 1 : 1, 2 : 1, 3 : 1, 4 : 1, 5 : 1, 6 : 1, and 7 : 1, respectively. (b) The stability of WSPL/siRNA complex of 2 : 1 in serum. (c) NR2B mRNA expression was tested by qRT-PCR as normalized to β-actin. (d) NR2B protein expression was analyzed by WB.
