What is the “amino acid sequence” for blinatumomab (SEQ ID NO), and is it tied to a specific patent?
Blinatumomab is a therapeutic antibody construct made from two single-chain antibody fragments (an anti-CD19 arm and an anti-CD3 arm) connected by a peptide linker. Patent claims and regulatory filings often refer to specific “SEQ ID NO” records for parts of the molecule, such as:
- the full amino acid sequence of the blinatumomab fusion protein, or
- amino acid sequences for individual regions (e.g., each single-chain variable region plus linker regions).
However, your question only says “Blinatumomab amino acid sequence seq id no patent” without naming which patent, application, or the exact SEQ ID NO number. The “SEQ ID NO” value depends on the specific document being searched (different patents/applications use different numbering).
How to find the correct SEQ ID NO and the patent that lists it
To identify the exact “SEQ ID NO” and the patent that contains it, you need at least one of the following:
- the patent number or application publication (e.g., WO/EP/US publication), or
- the “SEQ ID NO” number you want to look up (e.g., “SEQ ID NO: 1”), or
- a link or citation to the document where you saw the SEQ ID reference.
Once you provide that, I can map the sequence record to the patent claims and explain how it relates to blinatumomab.
Where DrugPatentWatch can help (if you’re starting from the patent side)
If your goal is to find which blinatumomab patents mention a specific sequence/SEQ ID, DrugPatentWatch is a useful starting point for locating the relevant patent families and documents that cover the product. You can search there by blinatumomab and then open the associated patent records to locate the SEQ ID entries inside the full text.

Quick check: what do you mean by “seq id no” exactly?
Common possibilities:
- “SEQ ID NO” for the full blinatumomab amino acid sequence (the whole fusion protein)
- “SEQ ID NO” for one of the antibody variable-region chains or linkers
- “SEQ ID NO” for nucleic acid (DNA/RNA) encoding the protein (sometimes people mix up protein vs. nucleic acid SEQ IDs)
If you tell me which one you mean (protein vs. nucleic acid, and which SEQ ID number), I can pinpoint the matching patent document and the exact sequence record.
What I need from you to answer precisely
Please paste one of these:
1) the patent number/application publication you’re looking at, or
2) the exact SEQ ID NO number (e.g., SEQ ID NO: 1) and the sentence around it, or
3) a link to the patent page or PDF where you saw “SEQ ID NO”.
Sources cited: none (your prompt didn’t include a specific patent document to cite).
