The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard. SC/T 7202.1-2007 monodon baculovirus diagnostic procedures - Part 1. tablet microscopy SC/T 7202.2-2007 monodon baculovirus diagnostic procedures part 2. PCR assay Principle 3 3.1 infectious hypodermal and hematopoietic necrosis virus and its epidemic characteristics Infectious hypodermal and hematopoietic necrosis virus (infectioushypodermalandhaematopoieticnecrosisvirus, IHHNV) particle size of 20nm ~ 22nm, is nonenveloped icosahedron, the cesium chloride buoyant density of 1.40g/mL, containing a line Like single-stranded DNA, the length of 4.1kb, capsid consists of four molecular weight were 74kD, 47kD, 39kD, 37.5kD polypeptide composition. IHHNV can be infected worldwide shrimp, shrimps infection fine angle (Litopenaeusstylirostris) can cause acute Biography Infectious diseases and high mortality (90%), the juvenile shrimp being the most serious hazards. IHHNV infection vannamei (Litopenaeusvannamei) Can cause chronic "little incomplete syndrome" (RDS), the main effect is the prevalence of shrimp slow growth, deformity, infected shrimp survival lifelong carriers of the virus, Spread through the vertical and horizontal. 3.2 Technical Principle IHHNV polymerase chain reaction (polymerasechainreaction, PCR) is IHHNV base section 389 (b) The length of the specific DNA sequence as a template, a pair of sequence specific oligonucleotide sequence complementary to the template at both ends as primers, the four The presence of deoxyribonucleoside triphosphate species, the use of synthetic DNA-dependent DNA polymerase, after dozens of denaturation, annealing and extension Extending reaction cycle, so that between the template DNA fragment obtained between the two primers specifically amplified series, and then by means of electrophoresis detection Measured to be specifically amplified fragment, which reveals the presence of trace IHHNVDNA.

4 Reagents and materials

In addition to the primer, the positive and negative controls, in accordance with the provisions of 4.1 reagents required SC/T 7202.2-2007 in Chapter 5. 4.2 100ng/μL Primer F. 5'-CGG-AAC-ACA-ACC-CGA-CTT-TA-3 ', - 20 ℃ to save. 4.3 100ng/μL Primer R. 5'-GGC-CAA-GAC-CAA-AAT-ACG-AA-3 ', - 20 ℃ to save. 4.4 positive control known IHHNV positive DNA template tissue sample, -20 ℃ preservation.
