Total RNA was isolated from in vitro activated lamina propria lymphocytes and used to direct the synthesis of cDNA. Interleukin 4 transcripts were then specifically amplified by PCR. Comparison of the nucleotide sequence with its human homologue demonstrates deletion within the coding region of pig interleukin 4 centred around amino acid residue 70 in the mature human protein.
从体外活化的固有层淋巴细胞中分离出总RNA,并用于指导合成cDNA。然后通过PCR特异性扩增白细胞介素4转录本。将该核苷酸序列与其人类同源物进行比较,结果显示猪白细胞介素4的编码区域内存在缺失,该缺失以成熟人类蛋白质中的氨基酸残基70为中心。
