Steve GisselbrechtIt’s a tough day but I do get to use my #1 favorite lab supply.
Gaurav Vaidya@stevegis_ssg Neat! What's normal about it?
The goats in question have not been immunized to make specific antibodies. Those antibodies are useful tools but will bind indiscriminately, so we first add preimmune ("normal") serum to block all the nonspecific binding spots.
@stevegis_ssg Very cool! Thanks for sharing.
