DEFINITION

Classification: 435/339.1

Binds a retrovirus or component or product thereof (e.g., HIV, LAV, HTLV, etc.):

(under subclass 339) Subject matter involving an animal cell which produces a monoclonal antibody or antigen-binding fragment thereof whose antigen-binding site(s) will combine with an integral or isolated part of a retrovirus, or with a substance shed by a retrovirus, such as a viral antigen.

(1) Note. Retroviruses are RNA viruses that encode the enzyme, reverse transcriptase, and are associated with acquired immune deficiency syndrome (AIDS) and related disorders, as well as with some forms of cancer, such as those caused by HTLV (human T-lymphotrophic virus) I and II, Rous sarcoma virus, MMTV (murine mammary tumor virus), feline leukemia virus, etc.
