Hepatitis B surface antibody (anti-HBs) levelcan be measured to determine if vaccination is needed. Following a vaccination regimen, anti-HBs can be measured to determine if protective immunity has been achieved. What is a titer test? An antibody titer testmeasures the amount of a specific type...

Post-booster seroprotection or vaccine response rates for all H exyon® antigens were numerically similar in groups A and B (Table 3) [6]. The proportion of participants with an antibody titer level of ≥ 8 1/dil for anti- MenA, anti-MenC, anti-MenW,...
Rabbit anti-b-tubulin antibody (#2146) was purchased from CST Japan K.K. (Chiba, Japan). The concentration used in immunofluorescence staining and Western blot analysis was in accordance with the recommended protocol for each antibody. Oil-red O staining Cultured cells were washed with PBS and...
It is believed that CD81, a tetraspanin family protein widely found on cell substrates, is involved in HCV entry, but requirements for other cell surface molecules on hepatocytes probably exist. Other proposed receptors include the LDL receptor, the class B type I scavenger receptor, mannose-...
RESULTS Kinetics of influenza B growth in MDCK and HepG2 cells. HepG2 monolayers were infected at various multiplicities of infection. Release into the supernatants of virus was quantified by plaque assay and HA titer. The results, shown in Figure 1, were compared with growth in MDCK cells,...
a greater portion of microscopic fields had detectable antigen in the nebulized lambs. The nebulization reduces viral titer by roughly one log (data not shown; manuscript under review) and thus may contribute to the decreased infectivity of nebulized inoculum; however, this likely affects both HEp-...
They received 3 additional doses of vaccine B at bimonthly intervals if they did not reach an antibody titer against hepatitis B surface antigen (anti-HBs) greater than 500 IU/L. Sixteen (8 in each group) of 20 patients (80%) responded (group I: median, 7,293 IU/L; range, 721-45...
In addition, the viral titer needs to be as high as possible to ensure that the cells are infected with highly efficient viral particles. Moreover, the efficiency of viral particles drastically drops by almost 50% if repeatedly freeze-thawed. This is overcome by snap-freezing single-use of ...
B, the virus titer of TFV in the supernatant of treated-HepG2 cells increased. The single step growth curves (Fig. 3C) showed that infectious virions in the supernatant increased after cells treated with 5 mM MβCD. Caveolin-1 is the principal organizer of caveolae. Knockdown of ...
