Input: Consider Input: Unlike these contaminant - responsive T cells , those that are truly specific for natural AChR epitopes appear less heterogeneous and therefore more suitable targets for selective immunotherapy .

Output: AChR epitopes

Input: Consider Input: We cloned the BamHI - F fragment from the left end of Ad4 in pUC13 - 1 between the SalI and BamHI sites in order to carry out the structural analysis of the E1A region of Ad4 .

Output: BamHI sites

Input: Consider Input: Developmental regulation of expression of the malate synthase gene in transgenic plants .
Output: malate synthase gene
