We provide an outline proposal to you defining how our service will meet your specific requirements and summarising all of the costs involved. There are no hidden extras. This proposal will form the basis of our service agreement, which will be approved by you, prior to project commencement.

 

We can provide you with custom-designed patient sample collection kits and can organise collection and transportation of your samples to and from our facilities using pre bar-coded packaging. Documentation can also be customised to suit your individual study requirements.

 

All samples are barcode labelled and registered into our custom built sample tracking database. The integrity and condition of the samples are checked against agreed specifications and any discrepancies are communicated to you prior to sample extraction.

 

All samples are stored in line with the agreed protocol. Our storage facility is located within a secure, controlled access area with constant temperature monitoring and backup capability.

 

The procedure used for nucleic acid purification will be determined in accordance with the sample type and condition. Customer-specified procedures can also be performed by our experienced service personnel. Scheduling ensures that samples are removed from storage and processed within a single working day. Barcode tracking is used throughout.

 

Purified DNA samples are quantified using either fluorescence (PicoGreen^®) or Absorbance (A260nm) techniques. Sample normalisation (to a defined volume, concentration or series of concentrations) is available using ‘state of the art’ automation.

 

We offer a number of methods for Quality Control analysis of the final nucleic acid product which can be tailored to suit your requirements. Options include Absorbance ratio determination, assay via PCR, agarose gel electrophoresis and restriction enzyme digestion.

 

After processing, samples are refrigerated prior to overnight despatch. Samples are returned with a full supporting data package in electronic or hard copy format. We can archive an aliquot of your sample in our cryogenic storage facility ensuring back-up materials are always available.
