    Hi, I'm Mr Hoan, I am working in the research and development department of Viet A Technology Corporation in Vietnam.
    Now, we need some DNA samples of pathogenic antigens to do some biological research projects in Vietnam. Our experiment is polymerase chain reactions, so we need some pathogenic antigens that are positive samples. Unfortunately, We don’t have enough positive DNA samples of pathogenic antigens for our experiment and we can’t find anywhere to purchase these products. I think you can produce these pathogenic antigens and provide them for us.
    We want to purchase some DNA samples of the pathogenic antigens products in human, including:
    −  The positive HPV specimen
    −  The positive HBV specimen
    −  Lamivudine-resistant rtM204I/V HBV, Lamivudine-resistant rtM180L HBV.
    −  Adefovir-resistant rtN236T HBV, Adefovir-resistant rtA181T/V HBV
    −  The positive HCV specimen
    −  HPV genotype high risk (16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, 82) and low risk (6, 11, 42, 43, 61, 70, 71, 78)
    −  HBV genotype A, B, C
    −  HCV genotype 3
    −  The positive CMV specimen.
    −  The positive specimen of  Isoniazid-resistant M. tuberculosis in mutant codon 315 of katG gene.
    −  The positive specimen of  Rifampin-resistant M. tuberculosis in mutant condon 516, 526, 531 of rpoB gene
    −  The positive specimen of  Ethambutal-resistant M. tuberculosis in mutant codon 306 of embB gene

    We also want to purchase some DNA samples of the pathogenic antigens in shrimp or fish, including:
    −  The positive WSSV (White spot syndrome virus) specimen
    −  The positive shrimp HPV (Hepatopancreatic  Parvo-like  virus) specimen
    −  The positive YHV specimen
    −  The positive TSV specimen
    −  The positive IHHNV (infectious Hypodermal  and  Haematopoietic  Necrosis) specimen
    −  The positive MBV(Nonodon Baculo Virus) specimen
    −  The positive NNV (Nervous Necrosis virus) specimen
    Please, supply us with these products if you have one.
    Actually, We have succeeded in the detection of pathogenic antigens in human and shrimp or fish by PCR technique.
    Now, we want to apply this successful to production process kit for the purpose of diagnosis in human and shrimp or fish. We have commercialized these products in heath sector. So, We need a manufacturer to provide us with these pathogenic antigens that are positive specimens in polymerase chain reactions.
    Please let us know the price of each product that we want to purchase,  and let us know how to pay the bill.
    Sure, We will cooperate with the manufacturer for long time in future, so you don’t hesitate to produce these pathogenic antigens to provide us.
    Thank you for your cooperation.
