*Swabs have also been used to collect DNA from a variety of samples
and surfaces, including drinking glasses, aluminum cans, phone
handles, earrings, car door panels, steering wheels, fingernails and
jacket cuffs. Protocols for DNA isolation from these swabs would be
similar to the buccal swab protocol.

Samples Requiring a Proteinase K Digestion
|
|
Table 2. Sample Types That Require a Proteinase K
Treatment Prior to DNA Purification Using the DNA IQ™ System. |
DNA from the following sample types has been successfully purified at Promega or
by external forensic laboratories. Due to the nature of casework samples, (i.e.,
samples may have been exposed to environmental factors for long periods of time,
and the amount of biological material may be limiting) DNA yields may vary and
DNA may not be obtained from all samples.
The following sample types require a Proteinase K digestion prior to the
addition of two volumes of prepared Lysis Buffer to one volume of sample when following the
Tissue and Hair Extraction Kit (for use with DNA IQ™)
protocol. See Technical Bulletin #TB307. A separate protocol for bone and antler
samples is linked below.
