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:

    $182 to Abcam for 1 mg of 98% pure rapamycin

    $245 to R&D Systems for 1 mg of 98% pure rapamycin

    $252 to Sigma for 1 mg of 95% pure rapamycin

    $439 to Calbiochem (EMD) for 10 mg of 99% pure rapamycin

          - or -

    $53 to LC Labs for 50 mg of >99% pure rapamycin!


Another example is cyclopamine:

    Among the many other cyclopamine suppliers, 19 suppliers charge $18 to $194 for 1 mg;
    only 3 suppliers claim >99% purity; 12 claim only 98%; and another 4 claim only 97%.

          - or -

    LC Labs' price for 25 mg of >99% pure cyclopamine is $84 — $3.36 per mg — 1/5 to
    1/64 of the cost from the suppliers noted above.

The picture is clear -- price tells you nothing about quality.
