    The stability of HBSAG is very good, and it can maintain consistent performance even under different experimental conditions, which gives me more confidence in the experimental results.

    02/10/2022

      HBSAG expression was high and could be easily detected.

      10/24/2020

        HBSAG performed very well in Western blot with clear bands, which improved the accuracy of the experiment.

        Q&As (6)

        Ask a question
        Can HBSAG protein test be used to evaluate the immune efficacy of hepatitis B vaccine? 06/12/2022

        Yes, the HBSAG protein test can be used to assess the immune efficacy of the hepatitis B vaccine. A positive result indicates that the immune system has developed a protective response against the hepatitis B virus.

        How important is HBSAG protein testing for screening for hepatitis B virus transmission? 11/04/2021

        HBSAG protein detection is an important means of screening for hepatitis B virus transmission, which can detect infected people early and take corresponding measures to interrupt the transmission chain of hepatitis B virus.

        Do HBSAG-positive people develop chronic hepatitis B? 06/11/2020

        Not all HBSAG-positive people will develop chronic hepatitis B patients, but HBSAG positivity implies HBSA virus infection and further assessment of the patient's liver function and level of HBV replication is required.

        What are the natural immunity associated with HBSAG protein? 10/31/2019

        The natural immunity associated with HBSAG proteins includes the immune response of natural killer cells (NK cells) and inflammatory cells.

        What is the sensitivity and specificity of the HBSAG protein test? 10/25/2019

        The protein tests are generally highly sensitive and specific, but there may be certain false negative or false positive results during early infection or chronic hepatitis B activity.

        What is the mechanism of HBSAG protein and hepatitis B virus infection? 08/21/2019

        The proteins are involved in viral replication, assembly, and release by binding to the core particles of hepatitis B virus.
