Synthesis of SP1-glycoprotein by the human placenta was directly demonstrated, by in vitro translation of RNA extracted from full term and from early placentas in a cell-free wheat germ system followed by specific immunoprecipitation of the radioactively labeled nascent peptides. De novo synthesized SP1-glycoprotein in both RNA preparations accounted for 1-1.3% of total protein synthesis.
通过在无细胞小麦胚芽系统中对从足月胎盘和早期胎盘提取的RNA进行体外翻译，随后对放射性标记的新生肽进行特异性免疫沉淀，直接证明了人胎盘合成SP1糖蛋白。两种RNA制剂中从头合成的SP1糖蛋白占总蛋白合成的1-1.3%。
