Purity and Price Are Not Correlated!

The prices charged by biomedical reagent vendors for a given product tell you nothing about the purity.

For example, as shown in our Purity/Price Comparison Table for Rapamycin you
can pay:

• $273.50 to Sigma for 1 mg of 95% pure rapamycin

• $189 to Calbiochem for 1 mg of 98% pure rapamycin

• $35 to LC Labs for 50 mg of >99% pure rapamycin,
  which is less than $1 per mg

Another example is cyclopamine:

• Among the many cyclopamine suppliers, 14 suppliers charge $88 to $840 for 1 mg; nine of those suppliers make no purity claim at all, and the other
  five claim only 98%

• LC Labs' price for 25 mg of >99% pure cyclopamine is $116 — 1/19th to 1/180th of the cost from other major suppliers

Please peruse some of our other Purity/Price Comparison Tables.  The picture is clear -- price tells you nothing about quality.
