background: monoclonal antibodies (mabs) are essential tools for many molecular im-munology investigations, epitope mapping and molecular modelling, clinical laboratory di-agnostic tests and immunotherapy. humoral immune response of immunized animals largely depends on the nature of antigen and the immunization technique. polysaccharides and heavily-glycosylated proteins are very elusive target...

The purpose of this study was to explore the correlations arterial-phase enhanced CT characteristics hepatocellular carcinoma (HCC) with differentiation degree and expressions proliferating cell nuclear antigen (PCNA) phosphatase tensin homologue (PTEN). Seventy-nine HCC patients who underwent three-phase dynamic contrast-enhanced before surgery were selected observe characteristics. tissue eva...

Hepatitis B virus co-infection with C and/or D is known to result in a more deleterious disease than chronic HBV mono-infection, resulting faster progression cirrhosis and hepatocellular carcinoma. This study aimed at determining the serological prevalence of infections among carriers frequency e Antigen tertiary hospital South-East, Nigeria. cross-sectional involving 72 consenting participants...

Serum samples of 9691 male adults had been collected and frozen for a prospective study of hepatocellular carcinoma in Taiwan. After an average follow-up period of 4.6 years, testosterone levels in the stored serum were measured by radioimmunoassay using commercial kits for 35 cases of newly developed hepatocellular carcinoma, 63 hepatitis B surface antigen-negative and 77 hepatitis B surface a...

Several monoclonal antibodies were raised against the human epidermoid carcinoma line A 431. The antibody produced by clone AR-3, when tested in enzyme-linked immunosorbent as say, was found to react with the cell line used as immunogen, the human gastric carcinoma line KATO III, the colon carcinoma line HT29, and the ovarian carcinoma line SW626. This monoclo nal antibody was found unreactive ...

We attempt to study the efficacy and adverse reactions of carboplatin, nab-paclitaxel regimen combined with atezolizumab in non-small cell lung cancer treatment. randomly selected 120 patients who received therapy our hospital from January 2019 December 2021 divided them into two groups, 60 cases respectively. Treated control group carboplatin paclitaxel pembrolizumab, while observation albumin...

PURPOSE To investigate TAP1, TAP2, and HLA class I antigen expression in primary ovarian carcinoma lesions and to assess the clinical significance of defects in the expression of these molecules. EXPERIMENTAL DESIGN Fifty-one formalin-fixed, paraffin-embedded primary ovarian carcinoma lesions were stained with affinity-purified rabbit anti-TAP1 and anti-TAP2 antibodies and with anti-HLA class...

An IgM class monoclonal antibody (MAb) was derived by immunizing BALB/c mice with a human endometrial carcinoma cell line. This MAb, termed C12, exhibited strong reactivity against endometrial carcinoma, but lesser reactivity against normal endometria. The antigen recognized by MAb C12 (C12 antigen) was detected by radiometric assay in sera from patients with various carcinomas, but not in sera...

Our previous immunohistochemical studies for the expression of MUC1 mucin antigen (which was detected by monoclonal antibody DF3) and MUC2 mucin antigen (which was detected by polyclonal antibody anti-MRP) in pancreatic and intrahepatic bile duct tumors demonstrated that invasive carcinoma with poor outcome showed a pattern of MUC1+ and MUC2- expression, whereas many of the noninvasive tumors w...

Merkel cell carcinoma (MCC) is a rare and aggressive cancer of the skin with ∼30% mortality. Around 80% MCC tumors originate from integration polyomavirus (MCPyV) DNA into host genome, leading to expression viral T-antigen oncoprotein ultimately, tumorigenesis. Though PD-1 pathway blockade has significantly improved outcomes for advanced MCC, many patients do not benefit or develop resistance t...
