I am looking for a method to remove residual EDTA from human plasma samples before the downstream use in cell culture. The goal is to minimize potential barrier disruption caused by EDTA remaining from blood collection. The only available information is that EDTA was used as the additive in the vacutainer tube, but the tube size or final EDTA concentration is unknown (maybe 18 mg in a 10 mL draw volume?).

Any suggestions would be greatly appreciated, thank you so much!
