Note: (A)The first step was to identify the 70th plate pools had a positive clone. (B)The second step was to screen the 70th plate and the 11th columm had a positive clone. (C) The third step was to screen the the 11th colummof the 70th plate and BAC-10 was identified as a positive clone. (P) was the positive control containing pig genomic DNA. (N) was the negative control containing ddH2O. M1: DL 2000 DNA ladder maker.
