Developing specific probes that distinguishes types and subtypes of viruses by a single probe will have a great impact not only in developing specific diagnostic reagents but also in developing tailor-made drugs and dosage requirements depending upon the genotype that cause the infection. We have selected aptamers specific for hemagglutinin protein of human influenza virus B/Johannesburg/05/1999. The selected aptamer, Class A-20, bind specifically to hemagglutinin of B/Johannesburg/05/1999 and able to discriminate it from hemagglutinin of human influenza A virus.

UI	MeSH Term	Description	Entries
D009981	Influenza B virus	Species of the genus BETAINFLUENZAVIRUS that cause HUMAN INFLUENZA and other diseases primarily in humans. Antigenic variation is less extensive than in type A viruses (INFLUENZA A VIRUS) and consequently there is no basis for distinct subtypes or variants. Epidemics are less likely than with INFLUENZA A VIRUS and there have been no pandemics. Previously only found in humans, Influenza B virus has been isolated from seals which may constitute the animal reservoir from which humans are exposed.

D015345	Oligonucleotide Probes	Synthetic or natural oligonucleotides used in hybridization studies in order to identify and study specific nucleic acid fragments, e.g., DNA segments near or within a specific gene locus or gene. The probe hybridizes with a specific mRNA, if present. Conventional techniques used for testing for the hybridization product include dot blot assays, Southern blot assays, and DNA:RNA hybrid-specific antibody tests. Conventional labels for the probe include the radioisotope labels 32P and 125I and the chemical label biotin.

D052156	SELEX Aptamer Technique	A method of generating a large library of randomized nucleotides and selecting NUCLEOTIDE APTAMERS by iterative rounds of in vitro selection. A modified procedure substitutes AMINO ACIDS in place of NUCLEOTIDES to make PEPTIDE APTAMERS.

D019267	Hemagglutinin Glycoproteins, Influenza Virus	Membrane glycoproteins from influenza viruses which are involved in hemagglutination, virus attachment, and envelope fusion. Fourteen distinct subtypes of HA glycoproteins and nine of NA glycoproteins have been identified from INFLUENZA A VIRUS; no subtypes have been identified for Influenza B or Influenza C viruses.
