Thank you for your interest in the reagents of Laysan Bio, Inc. Below is a list of the categories of reagents that we offer. To find out more information about our reagents, please go to our FAQ page.
Don't know which PEG to use? Laysan offers research kits to help reduce the cost and time determining which functional group and MW is appropriate for your application. The kits consist of multiple functional groups that will react with a specific targeted end group or with multiple MWs of a single functional group. Individual kit information is available on our kit page.
If you do not see a reagent below that will fit your needs, please contact us to receive a custom quotation. If you need a quote for quantities larger than 50 grams, please contact us for bulk pricing. We offer smaller bottling requests for a fee of $50 and then $5 per bottle.
