It’s a tough day but I do get to use my #1 favorite lab supply.
@stevegis_ssg Neat! What's normal about it?

@gaurav

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.
@stevegis_ssg
Great band name.
And now, live on stage...
@stevegis_ssg That sounds like something out of a 1930's horror movie.
@stevegis_ssg Checks out. This goat serum appears perfectly cromulent.
