The reason for using ELISA for detecting virus or viral antigens. Introduction: ELISA −Enzyme Linked Immunosorbent Assay is the immuno assay used for detecting suspected antigens for specific antibodies or for detecting suspected antibodies in a sample. Here the antigen is coated on to the well and the primary antibody is added. If there is specificity an antigen-antibody interaction takes place. Then another enzyme labelled secondary antibody is added to which the substrate specific to the enzyme is introduced. If there is enzyme substrate complex formation, then a coloured product is formed. The intensity of the colour change is directly proportional to the amount of antibodies present.

According to a recent study, 1 out of 50,000 people will be diagnosed with cystic fibrosis. Cystic fibrosis can be caused by a mutant form of the CFTR gene (dominant gene symbol is F and mutant is f). A.

Kinetics: One-Compartment First-Order Absorption 1. In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple routes of administration provides greater insight than a single route of administration alone. The following data was collected in 250-g rats following bolus IV, oral (PO), and intraperitoneal (ip) administration. Using this data and set of graphs, determine:(calculate for each variable) (a) k, C0, V, and AUC* for the bolus iv data (b) k, ka, B1, and AUC* for the po data c) k, ka, B1, and AUC* for the ip data (d) relative bioavailability for po vs ip, Fpo/Fip (e)absolute ip bioavailability, Fip (f) absolute po bioavailability, Fpo
