Linscott's Directory of Immunological & Biological Reagents

Linscott's Directory has been connecting biotech researchers with reagent suppliers since 1980.

Use our search engine to find antibody suppliers for thousands of specific antibodies. Plus locate sources for ELISA assay kits, cytokines, enzymes, recombinant proteins, siRNAs, tissues, organs, custom antibody services and more. We currently have more than 2,100,000 different listings in our antibody section, and more than 1,000,000 listings of other products and services available from hundreds of different commercial and governmental sources worldwide, and more are being added each week. Let us connect you directly to the companies and institutions that carry the products and services you need.

What's New?

The New Year

Linscott's Directory has had a very busy beginning to 2017. Over the last couple of months, almost every supplier in the Directory has submitted updated product information for their listing. That means tens of thousands of brand new antibodies, antigens, assays and more are now available to you, via our fast and simple search functions.

A good number of the new products and services we include come from these newly listed suppliers: Affinity Immuno, Bioss Antibodies, Crystal Chem, Enquire Bioreagents, and Rapid Novor. Look for their products in your search results, and, if you communicate with them, please let them know that you found them in Linscott's Directory.

Antibody Validations

We are pleased to announce a new collaboration with our friends at that allows us to post user reviews of antibodies within Linscott's Directory. As we are all aware, there are many possible sources for most antibodies, but the quality and suitability for your particular application can be difficult to determine in advance.

It is our hope that Linscott's Directory and can help the research community in this regard, by simultaneously providing comprehensive antibody supplier listings and a convenient method to both review other researchers' reports and to submit your own experiences with specific antibodies. When a pAbmAbs user review exists for an antibody in Linscott's Directory, you will see a "Review Available" note in our search results table. A brief summary is available in the Directory by clicking on the "Review Available" text, and the full review is available by then following the link to

We hope that you find this new feature helpful, and would like to hear any comments about it that you may care to offer.

Thank you for using Linscott's Directory.

Additionally, we are pleased to present brand new listings from five new suppliers: AAT Bioquest, Amar Immunodiagnostics, BioFront Technologies, Buhlmann Diagnostics, and Pyxis Laboratories. Look for their products in your search results, and let them know you found them in Linscott's Directory.
