The invention provides an LPS-binding and -neutralizing peptide comprising the amino acid sequence X-1-2-3-4-5-6-7-8-9-10-11-12-13-14-Y wherein:, X is a linear chain from zero to four amino acids. (1) is one of the amino acids alanine threonine, glutamine, asparagine or, serine; and if and only if at least one of the a.a. at positions +5 +9, +10, +11 or, +13 has been replaced (from the native LBP sequence) according to what is herein described, then (1) could also be arginine or lysine. (2) is one of the amino acids alanine valine, isoleucine, leucine, phenylalanine methionine, tryptophan or tyrosine. (3) is one of the amino acids glutamine asparagine, serine or threonine. (4) is one of the …

Why it's free to use
- Filed June 6, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 6, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 6, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
