Netters,
We are attempting to produce immunogens from bacteria by killing them
with glutaraldehyde first.  Unfortunately, the protocols that we are
following from the mid-80's refer to cell culture densities in terms of "NIH
units of opacity".  Can anyone relate this to OD units?

Thank you in advance,
Ken
