polyanion heparin

[Byung-hoon Kim]

Dear Netters.
I'm planning to do chloroplast run-on transcription and I have read some
articles on the thesis. In one of those articles, I encoutered a reagent
called 'polyanion heparin', which was used as an RNase inhibitor.
I looked up some catalogues (SIGMA and ICN) and the Merk Index
But I can't find it anywhere.

Would you please help me to find what kind of reagent it is,
and how I can buy it.
