I will be using blood serum for the Luminex assay. I was wondering if I can freeze the samples before doing the Luminex I mean can LUMINEX analysis be performed after samples are frozen and thawed?
We have never had problems in freezing/thawing serum. I suggest aliquoting and freeze and thaw once your samples before use (do it directly on a 96 well plate, you will gain A LOT of time). You will give your samples the same treatment and if degradation happens, it will happen to all samples.
