Immunogold labeling-induced synergy effect for amplified photoelectrochemical immunoassay of prostate-specific antigen.

Age Specific Reference Levels of Serum Prostate-Specific Antigen, Prostate Volume and Prostate Specific Antigen Density in Healthy Iranian Men

Background: It is relevant to highlight that there is not a precise and perfect report on either 95 percentile value (upper limit of normal range) or on appropriate reference intervals for serum PSA in Iranian population. Objective: To determine age-specific reference ranges for serum prostate-specific antigen (PSA) concentration and PSA density (PSAD) and prostate volumes in a population of he...

Effect of concurrent training (endurance-resistance) on serum level of prostate specific antigen (PSA), cardiorespiratory endurance, muscular strength and body composition in men over 50

Age-Related Prostate Specific Antigen Reference Ranges in Healthy Northern Iranian Men

Background: Prostate cancer is the third most common malignancy in men worldwide. Despite being a helpful biomarker in prostate cancer, prostate specific antigen (PSA) is affected by different factors including age, lifestyle, geographical region and ethnicity. Objective: To determine the age specific serum PSA level among healthy Northern Iranian men and to compare the results of our study wit...

Preparation of prostate specific antigen standards for immunoradiometric assay

Background: Immunoradiometric assay is one of the most common and precise methods for determination of prostate specific antigen (PSA) in clinical laboratories. Usual use of human serum in routine assays has many disadvantages such as easy contamination and precipitation, instability and unavailability. Thus in order to avoid these problems the artificial matrix was used which acts sim...

Measurement of Affinity Constant of Anti-human IgG Monoclonal Antibodies by an ELISA-based Method

Background: The affinity of an antibody to its antigen is a crucial parameter in its biological activity and performance of an immunoassay such as ELISA. Affinity of most IgG specific MAbs are often determined by methods which require labeling of either antigen or antibody, and are sometimes difficult to control, do not always lead to the expected signal and often result in immunological modifi...
