  • Patent protection for antibodies per se , on the other hand, may be obtained using patent claims that define the antibodies on the basis of their structural and/or functional properties, their use, for example, in specific medical treatments, and/or their method of production. (vennershipley.com)
  • Both in Europe and the U.S., antibody patent claims that refer directly and exclusively to the amino acid sequences of the antibodies provide potentially the most robust patent protection for specific antibodies, albeit at the expense of claim breadth. (vennershipley.com)
  • For example, if the data are available, then it may be possible to obtain patent claims for sequences based on a level of sequence identity, variability in specific regions, or alterations in selected amino acids of the antibody. (vennershipley.com)
  • Internalization of antibodies by specific (target mediated) or non-specific (e.g. pinocytosis in endothelial cells) mechanisms forms a key determinant of the half-life in the body, and even subtle changes to the structure of monoclonal antibodies can result in considerable changes to the duration of activity. (news-medical.net)
  • We actively pursue industrial collaboration to further develop our therapeutic antibody candidates. (a-star.edu.sg)
  • An isolated antibody comprising a VL domain comprising the amino acid sequence of SEQ. (vennershipley.com)
  • This type of patent claim, which is sometimes referred to as an "epitope claim", has historically been widely used because it provides the possibility of obtaining broad protection for any antibody binding to the same epitope, regardless of the antibody sequence. (vennershipley.com)
  • The Company is exploring various indications across the spectrum of GBA1 mutations, including Parkinson's disease, Lewy body dementia, and Gaucher disease, as well as vectorized antibodies to explore undisclosed indications in neuro-oncology. (biospace.com)
  • Reinfection after previous spontaneous or treatment-related viral clearance: Obtain initial HCV-RNA testing (because an HCV-antibody test is expected to be positive). (medscape.com)
  • A small phase I clinical trial has tested an anti-HIV strategy involving an adeno-associated viral vector-based gene delivery system that instructs cells to pump out antibodies that block HIV. (sciencedaily.com)
  • An alternative anti-HIV strategy called Vectored ImmunoProphylaxis (VIP) designed by researchers at the Ragon Institute of MGH, MIT and Harvard and Massachusetts General Hospital (MGH) involves an adeno-associated viral (AAV) vector to deliver instructions to muscle cells to pump out antibodies that block the virus. (sciencedaily.com)
  • The trial also showed that REGEN-COV, which is a combination of monoclonal antibodies casirivimab and imdevimab, shortened COVID-19 symptom duration and reduced viral levels, the company said in a statement . (ktvu.com)
  • however, dried blood spot (DBS) samples offer an innovative approach of sample collection with several advantages over traditional phlebotomy. (labroots.com)
  • By addressing diverse medical needs, Nona is ensuring that their innovative antibody discovery techniques have a far-reaching impact. (tefwins.com)
  • As Nona Biopharma continues to pioneer innovative approaches in therapeutic antibody discovery , the future holds great promise. (tefwins.com)
  • This innovative solution provides an easy, turnkey means of evaluating the internalization of significant numbers of antibodies. (news-medical.net)
  • For antibodies named until early 2017, the substem preceding the stem denotes the animal from which the antibody was obtained. (wikipedia.org)
