Re: [Histonet] Chicago Sky Blue stain vs. KOH - striking comparison

2011-11-11 Thread John Kiernan

The names Chicago blue and sky blue have been applied to various disazo dyes 
used in the past for direct dyeing of cotton. 
The name Chicago sky blue does not appear as a principal name or a synonym in 
either the 9th (1977) or the 10th (2002) editions of Conn's Biological Stains. 
In Conn9, there is a reference for staining fungi (Kuranz 1964) with ink blue, 
which was believed to be Chicago blue 6B (CI 24410, Direct blue 1).  This dye 
has also been used to quench autofluorescence prior to immunofluorescent 
staining, often as pontamine sky blue 6B or Niagara blue 6B. Closely related 
dyes are Chicago blue 4B (CI 24395, also called benzo sky blue 2B and brilliant 
benzo blue 6B) and benzo sky blue (CI 24400, Direct blue 15, also called sky 
blue and pure blue). 
 
Probably Chicago blue 6B (CI 24410, Direct blue 1) is the only one of these 
likely to be available. In the 1970s it was still an article of commerce with 
more than 70 brand names, but by 2002 it was no longer used industrially. The 
CI number and application name are the best identifiers, but remember that dyes 
often are mixtures and sometimes are mislabelled. None of these blue disazo 
dyes are certified by the Biological Stain Commission.

 Does anyone have ordering information for a stain called Chicago Sky
 Blue(CSB)?  I just saw an article in the NOV issue of ASCP LABMEDICINE
 (page 649) comparing KOH vs. CSB and, wow, is that a beautiful stain.  
 
  
 
 The results were dramatic, with about a 25-50%  increase in the
 Dermatophytes identified and about a 5X increase in the Pityriasis
 versicolor identification.
