Introduction: Solid Phase Extraction (SPE) is a powerful sample-preparation technique widely used in pharmaceutical analysis to isolate, concentrate, and purify analytes from complex matrices. This introduction covers the principle — selective adsorption and desorption on sorbents (C18, HLB, ion-exchange, mixed-mode) — and the stepwise procedure: conditioning, sample loading, washing, drying, and elution. Key factors such … Read more

Introduction Radioimmunoassay (RIA) is a highly sensitive immunoanalytical technique used in B.Pharm to quantify hormones, drugs and biomarkers by competitive binding between a radiolabelled tracer and unlabeled analyte for a limited antibody. Key methods include competitive and solid‑phase separation, using radiolabels such as iodine‑125 and gamma counting to measure counts per minute (CPM). Important concepts … Read more

Radio-Immunoassay (RIA) is a highly sensitive analytical method that quantifies trace amounts of hormones, drugs, and biomolecules by competitive binding between radiolabeled tracers and unlabeled analytes for a specific antibody. Principles and components of RIA include antigen–antibody interactions, radiolabeled tracer, separation techniques, detectors, standard curves, and quality control. B. Pharm students should understand radioisotopes (e.g., … Read more
