Product Quality Discussion
Product identity and purity are important! At LC Laboratories we take great care to provide products of the highest purity and activity.
Low price does not mean low purity. LC Laboratories' prices are often 30-80% lower than those charged by other suppliers, especially for the most widely used products such as kinase and phosphatase inhibitors and activators. However, our lower prices do not signify that our product purities are lower as well. Quite the opposite: we believe that the purity of each of our products is equal to, and in most cases greater than, the purity obtainable from any other source worldwide.
Our manufacturing advantages. While it may be a little difficult to see how that is possible higher purity for a lower cost the reason is simple. We manufacture all but a few of our products ourselves, and we have large-scale preparative liquid chromatography purification capabilities. Over the past 33 years we have developed numerous proprietary, very efficient, low-cost production methods that have been optimized to provide very high final purity. We have also located very low-cost sources of raw materials for our manufacturing.
No middlemen for manufactured products. When you purchase directly from LC Laboratories, there is no additional cost for a middleman. When middlemen such as our larger competitors buy and resell products, usually that introduces a two- to ten-fold increase in the product cost.
Intense focus on purity. We also take extraordinary care to study and verify the purity and stability of our products. This is extremely important, because many popular products have subtle purity or stability problems that other vendors often ignore. Examples include okadaic acid products, calyculin A, chelerythrine, phorbol esters, and bafilomycin A1. (More information about these products and the special problems associated with them is presented below.)
Small number of products means more attention to each product. LC Laboratories currently offers only about 174 products. Thus, we are able to pay a lot more attention to each product's production and final purity than companies offering thousands of products. To be more specific, we sell (on average) a lot more of each of our products, particularly in terms of milligrams or grams, than do other companies having thousands of products. So, we can spend more time per compound being sure that the purity is what it should be.
Also, our prices are low because:
we don't rent expensive booths at trade shows
we don't publish massive catalogs in expensive rainbow colors
we don't hire outside contractors to build our website; Dr. Kevin Doyle, our biochemist, created it
we don't place full page, full color ads in journals such as Science and Nature
we don't spend our (your) money on "free" mugs or T-shirts
The prices charged by biomedical reagent vendors for a given product tell you
For example, as shown in our Purity/Price Comparison Table for Rapamycin you
$284.50 to Sigma for 1 mg of 95% pure rapamycin
$199 to Calbiochem for 1 mg of 98% pure rapamycin
$53 to LC Labs for 50 mg of >99% pure rapamycin, which is about $1
17 suppliers charge $18 to $210 for 1 mg; nine of those suppliers make
LC Labs' price for 25 mg of >99% pure cyclopamine is $87 1/5 to

MORE ABOUT PURITY
We are aware of many instances where unrecognized purity problems have led to large amounts of research work being compromised or even rendered useless due to spurious results from substandard reagents.
Here are some examples of product purity or activity problems in the signal transduction reagents business:
Our products are for laboratory research only and are sold only to qualified research institutions, not to individuals or patients nor for veterinary use.
