Arena Stage and Invitrogen Logos - Have you seen this font they share?

You've probably seen this font before. Work for [[|Arena Stage]] theater in D.C. has been featured in design annuals for several years. The same typeface used in the Arena Restaged logo (I believe) is used in this logo for Invitrogen, a biotech company.

Can anyone help me ID this font?



Oh my. You're GOOD.

You found in a minute and a half what I failed to find in an hour.

Many, many thanks.

Just one of those faces that is burned on my memory. :^) You're welcome.
