June 22

Today we started the long process of separating out the nucleosomes from the red blood cells. we began by washing and centrifuging the red blood cells 4 times until basically the red had separated and we were left with a semi snotty mixture. we then cleaned the snotty nucleosomes again and collected the final solutions and combined them. We then added a mixture that broke up the nucleosomes and made them less gooey and then centrifuged again and took the liquid that was left over and tested the absorption of the leftovers and got a strange step graph where 260 nm was the middle stem. We are currently adding a salt mixture and about to do more centrifuging
