Binary Bacterial Artificial Chromosomes (BiBAC) are large insert cloning vectors that contain the necessary features required for Agrobacterium-mediated transformation. However, the large size of BiBACs and low-copy number in Escherichia coli (DH10B) and Agrobacterium tumefaciens make cloning experiments more difficult than other available binary vector systems. Therefore, a protocol that outlines preparation, modification, and transformation of high-molecular weight (HMW) constructs is advantageous for researchers looking to use BiBACs in plant genomics research. This unit does not cover the cloning of HMW DNA into BiBAC vectors. Researchers looking to clone HMW DNA into BiBACs can refer to Zhang et al. (2012; doi: 10.1038/nprot.2011.456).
