METHOD OF PRODUCING HOUSE DUST MITE (DERMATOPHAGOIDES) ALLERGEN Russian patent published in 2008 - IPC A61K39/35 G01N33/53 

FIELD: medicine, pharmacology.

SUBSTANCE: method comprise salt-water extraction from raw material using Evans-Cook extraction liquid, mites cultivation during from 3 to 4 months, at temperature 25±2°C and relative air humidity 73±3%, on house dust and bristle. As initial basis, the mix of house dust mites Dermatophagoides farina or Dermatophagoides pternissinus culture and culture medium, including excrements, cast off skins, and food debris, is used. Salt-water extraction from raw material is performed during three days, after mixing it and homogenization with glass powder; the maintained incubation temperature is 2° to 10°C; the extraction material being shaken for 30 minutes three times a day with 1.5 hour intervals. Extraction completed, the supernatant liquor is decanted and centrifuged at 5000 to 6000 rpm for 30-40 minutes, then it is filtered through paper filter; in consequence sterilization through filtering, 3 to 4 months mother solution stabilisation, and bottling are carried out; the finished preparation is produced.

EFFECT: invention provides producing high effective treatment allergen in simplified process technology.
