Quantification of HBV core DNA was performed using real-time PCR. HBV cccDNA extraction and analysis Equal numbers of cells were collected in Eppendorf (EP) tubes and lysed in 500 μl of SDS lysis buffer at 37 °C for 20 min. Then, 125 μl of 2.5 M KCl was added to each tube, ...
We used the Cas13a-crRNA system in conjunction with colloidal gold test strips to detect HBV DNA rapidly and portably. The following is the “elimination method” strip detection of HBV DNA principle (Figure 4(a)): The test strip was constructed containing a sample pad, conjugation pad (with...
PCR has fine specificity and sensitivity in detecting HBV DNA, but it is more expensive and time-consuming compared with ELISA. So It's clinical practice Is limited some way.rnAmplifying HBV DNA with capillary plastic tube, We consume only half reagent of that with Eppendorf tube, and spend ...
Hepatitis B virus DNA (HBV-DNA) serves as a crucial biomarker for the detection of the hepatitis B virus, with variations in its concentration in blood samples providing vital insights into patient infection and recovery status. We have developed an electrochemical biosensor tailored for HBV-DNA de...
(Qiagen, Valencia, CA, USA). Total HBV DNA, cccDNA and human genomic DNA were quantified with the Invader® methodology (Third Wave Technologies, Inc., Madison, WI, USA) as described[7-10, 17]. HBV DNA was extracted from serum and quantified with the COBAS Amplicor HBV Monitor Test ...
e Liver HBV-DNA was detected. The value of the undetectable Q-PCR sample was assigned as the detection limit for plotting. Statistics: Student’s t-test. *, p < 0.05; **, p < 0.01; ***, p < 0.001; LoD, limit of detection Full size image Fig. 3 TVGV-HBx induces...
Brief Nucleic Acid Test Kit for HBV, HCV, HIV (Type1+2), is based on real-time fluorescence PCR technology and used for nucleic acid qualitative detection of HBV, HCV, HIV1+2 in plasma. This kit is intended for use as a blood donor screening test to detect HBV DNA, HCV RNA, HIV-...

Chronic HCV infection should be confirmed with RNA detection8,9 while HIV antibody reactivity should be confirmed by an additional two serology reactive test results for a HIV-positive diagnosis10. HBsAg is the earliest indicator (besides HBV DNA detection) of HBV acute or chronic infection, may ...
