The below article will explain how to search CDRs on PatSnap Bio.
To access CDR searching, first you must select CDR tab on the starting page.
Here you can now enter the CDR sequences you wish to search. Once you are happy with your input and the preferences on the right side of the page you can proceed to the result page by hitting search.
On the left highlighted in red you can see the number of patents the CDRs have matched to and which patents contain more than one of the CDR inputs.
For this example only CDR 1 and CDR 3 are found together in 112 patents.
You can use this to refine your results to see only patents with both CDRs.
In the middle body of the page you will find the alignment of where these CDR's are found and how they align with the sequences found.
Once you are happy with the refinements you have made you can click on the View Patents button to direct yourself to the patents containing those results.
