2 different samples: term placenta and cultured term cells. Using one antibody with two controls: rat brain and human brain.
I get a band at expected mwt in term placenta and rat brain but then when I use human brain and cultured term cells I get a matching higher mwt band in both the human brain control and cultured cells.
All of these bands disappear with preabsorption!
I hope this is clearer.
