What should I do if cryoprecipitates form while thawing a frozen plasma sample?
FAQ ID - 3646

If cryoprecipitates cannot be resolved completely by vortexing, the sample should be centrifuged to prevent precipitates from blocking the column. To ensure that no cfDNA is co-precipitated,  centrifugation can be performed at a lower speed (at 6,800xg for 3 minutes at room temperature, as stated in the Protocol Sheet for the QS DSP Circulating DNA Kit).
