The antagonistic Streptomyces-PR15 is a broad spectrum against various plant pathogenic fungi and bacteria of economic crops. To develop the ELISA technique for detection the Streptomyces-PR15 in bioproducts and plant surrounding environment, the production of polyclonal antiserum against Streptomyces-PR15 was carried out. The antigen prepared from Streptomyces-PR15 whole cell proteins was mixed with Freund’s incomplete adjuvant (1:1, v/v) was injected to in New Zealand White rabbit with immunization program as follows, intramuscular injection for 3 times then only antigen was intravenous injected for 2 times. Bleeding was done at 10 days after final immunization and then at weekly interval for 8 weeks. The antigen was re-intravenous injected at 14 days... |
