You've performed a haemocytometer count and have determined that there are 1.92 × 10⁸ cells/ml in your 2 ml of cell suspension.

In the MHC restriction of T cells experiment you will need to make up a 1 ml aliquot of 1 × 10⁶ cells.  You will need to remove μl of cell suspension and add μl of buffer to make up this cell suspension.

(Answer to 2 decimal places.)
