Biobank

Investigating officers find this method very helpful in investigating crimes. The DNA samples taken can be compared and there have been many instances where crimes were solved just by the proof given by these samples. Portraits of the criminal can be made using these samples which speeds up the investigation process. This is very simple and affordable process. A biobank or a biorepository is the place where these DNA samples are stored. Yet another method is using the DNA specimens which can be had from blood samples or cheek cells. This is then sent to the laboratory for analysis. Generally the process is repeated and then only the report made after confirmation of results. In cases where the samples have to be taken to distant places the cold chain management plans the transfer so that the specimens or samples are not damaged or destroyed in any way. In the labs analyzing process is done with aliquots which speed up the procedure. In a bio bank detailed and careful tagging of the samples is vital as any wrong comparison or analysis will completely change the investigating case. Code numbers should be given for proper identification and then only placed in the freezer compartment.
