25. r than 50 pg mL may need to be processed several times before the entire sample is fragmented to the desired length Diagenode suggests that high concentration samples be diluted in TE buffer down to 50 pg mL prior to processing Additionally the viscosity of DNA solutions containing very high molecular weight genomic DNA can be slightly reduced by rapidly pipetting the sample to begin the fragmentation process before submitting the sample to the Megaruptor The Megaruptor is designed to process sample volumes between 50 ul and 400 ul It is recommended to use a minimum sample volume of 100 250 ul for 2 kb fragments If the sample volume exceeds this range after dilution it can be split into two or more aliquots for shearing In this case a new Hydropore is not necessary Simply reuse the same Hydropore for each subsequent aliquot of the same sample The number of times a Hydropore can be reused depends on the purity of the sample being sheared Shearing small volume samples 75 pl at high speeds targeting fragment sizes 2 kb can lead to larger than expected fragments This is likely due to small bubbles decreasing the effective flow rate and the pump having difficulty accelerating to the required speed over very short stroke lengths The unexpected increase in fragment length is typically not more than 300 bp but the user should be aware of this possibility PAGE 9 Diagenode Inc North America Phone 1 862 209 4680 Fax 1 862
26. ring performance If larger bubbles are present in the syringe and they do not disappear when the aspiration step is completed it is possible that shearing performance will be affected Typically this is caused by a dirty syringe or loose connections Check and tighten all fluidic connections Perform a syringe wash If more stringent washing is required follow the manufacturer s advice on maintaining the syringe as described in chapter Maintenance If none of these measures are successful the seal on the syringe may have been compromised and the syringe should be replaced Q During the sample load step and subsequent shearing steps the sample is not being fully drawn into the syringe A This is most likely caused by a sample with DNA concentration in excess of 50 pg mL The sample is too viscous to be drawn into the syringe in the time allotted In some cases shearing a sample with very high concentration multiple times will result in satisfactory performance However Diagenode recommends diluting samples to 50 pg mL This may also be due to a dirty or contaminated sample causing the Hydropore to clog Asample with many suspended particles proteins or cellular debris can clog the Hydropore See the section on Sample Preparation for guidelines Q The DNA fragments are not the expected size A The software is calibrated to consistently provide reproducible results regardless of sample conditions One exception is shearing small volum
