[Histonet] RE: My bit of trivia for today - True Blue

[Connolly, Brett M]

Interesting Tim....

My true blue story dates from several years back when I was working up some multiplex IHC staining using 2 HRP substrates.

One was DAB and the second was True Blue Substrate from KPL Labs. It worked quite nicely, but is alcohol/xylene soluble so one needs only to wash in water and air dry before coverslipping.

Subject: [Histonet] My bit of trivia for today - True Blue

I was listening to the Wait Wait Don't Tell Me radio show this weekend and they had to come up with the derivation of "True Blue" as a saying. Turns out it had to do with blue dye colorfastness. Later they would call it Fast Blue - but that does not convey the later meaning of the phrase..


'True blue' is supposed to derive from the blue cloth that was made at Coventry, England in the late middle ages. The town's dyers had a reputation for producing material that didn't fade with washing, i.e. it remained 'fast' or 'true'. The phrase 'as true as Coventry blue' originated then and is still used (in Coventry at least). The town's standing was recorded in 1670 by John Ray in the first edition of A Compleat Collection of English Proverbs:

"Coventry had formerly the reputation for dying of blues; insomuch that true blue became a Proverb to signifie one that was always the same and like himself."
