Immune checkpoint antibody-mediated blockade has gained attention as a new cancer immunotherapy strategy. Accumulating evidence suggests that this therapy imparts a survival benefit to metastatic melanoma and non-small cell lung cancer patients. A substantial amount of data on immune checkpoint antibodies has been collected from clinical trials; however, the direct effect of the antibodies on h...

Antibody drug conjugates (ADC) are an emerging class of pharmaceuticals consisting cytotoxic agents covalently attached to antibody designed target a specific cancer cell surface molecule followed by internalization and intracellular release payload exhibit its anticancer activity. Targeted delivery variety cells has been demonstrated have significant enhancement in clinical efficacy dramatic r...

Abstract Background There is a decrease in vaccine-specific antibody to certain vaccine-preventable diseases in children after chemotherapy, but the frequency of non-immune patients is not clear. In the present case-control study, was taken under investigation protection level to Hepatitis B infection in children 6 months after completing chemotherapy. Materials and Methods In this study 6...

hepatitis b virus (hbv) infection and its sequelae such as cirrhosis and hepatocellular carcinoma has remained a serious public health problem throughout the world. the who strategy for effective control of hbv infection and its complications is mass vaccination of neonates and children within the framework of expanded programme on immunization (epi). vaccination with hepatitis b surface antige...

We present a solid-phase immobilization method for radioligand assays, using an immunoadsorption coating procedure of anti-triiodothyronine rabbit IgG (anti-T3 IgG) onto second antibody (sheep anti-rabbit IgG) covalently bound to Amino-Dylark beads. The second antibody was in excess, compared with the first antibody, thus eliminating reproducibility problems between immunoadsorptions. Beads coa...

The contributions to Aleutian disease gammopathy of specific antiviral antibody and an autoimmune component, anti-DNA antibody, were studied with pastel ranch mink naturally infected with Aleutian disease virus. Specific antibody activities were determined by countercurrent immunoelectrophoresis and radioimmune assay, respectively. Gamma globulin levels (percent gamma) were determined by serum ...

background: in spite of available, and sensitive screening assay for detection of hepatitis b virus surface antigen (hbsag), occasional cases of post-transfusion hepatitis b virus infection are still observed. the aim of the present study was to assess the prevalence of positive anti hepatitis b core (anti-hbc) and presence of hbv-dna in serum sample of healthy blood donors negative for both hb...
