Hybridization Protection Assay

[Udo Reischl]

Greetings to the members of this most active newsgroup,

I have plans to evaluate the "hybridization protection assay" test 
format for the high sensitive detection of bacterial pathogens. This 
assay format is somehow associated with Gen-Probe Inc., San Diego and 
was published in 1989 by L.J. Arnold (Clin. Chem. 8, 1588-1594) . 
As a prerequisite for this assay I am looking for oligonucleotide probes 
labeled with a special acridinium ester: 

 4-(2-succinimidyloxycarbonylethyl)phenyl-
10-methylacridiunium-9-carboxylate fluorosulfonate

Is this label commercially available in form of an aminolink 
component (as stated above) or does any company out there 
offer the custom DNA synthesis of oligonucleotides with such a 
modification ?

Thanks for any hints or suggestions,

Udo.
