Detection of immunoglobulin heavy chains by LC-MS/MS of gel-purified tissue lavages, extracts and secretions.

Samples were run on separate gels and bands were excised from the region predicted to comprise the immunoglobulin heavy chains (50–80 kDa). Gel images are presented in Figure S2.

样品分别在不同凝胶上进行电泳分离，随后从预测包含免疫球蛋白重链（50–80 kDa）的区域切取电泳条带。凝胶图像详见补充图S2。
