Bacterial Artificial Chromosomes (BAC) have been developed to accommodate much larger pieces of DNA than plasmids can. To provide maximum information and utility, a BAC library is generally organized into a map that reflects the DNA sequence in a chromosome. The high-throughput BAC fingerprinting screening using the Prism® SNaPshot® Multiplex Kit is an effective, easy, and cost-efficient solution that has been validated on the Life Technologies 3730/3730xl DNA Analyzers to map BAC libraries.

Step-by-Step Guide to BAC Fingerprinting

DNA Purification kit

DNA extraction is a critical first step in the experimental workflow of DNA Sequencing and Fragment analysis. The overall quality, accuracy and length of the DNA sequence read can be significantly affected by characteristics of the sample itself, and the method chosen for nucleic acid extraction. Ideal methods will vary depending on the source or tissue type, how it was obtained from its source, and how the sample was handled or stored prior to extraction.

Recommended Product: DNA Isolation

The restriction ends are labeled by incorporation of a fluorescently-labeled dideoxynucleotide complementary to the informatory first base at the 3' end.

Capillary Electrophoresis

During capillary electrophoresis, the products of the PCR are injected electrokinetically into capillaries filled with polymer. High voltage is applied so that the fluorescent DNA fragments are separated by size and are detected by a laser/camera system.
