Which of the following is not a method used for imaging radioactive material?

Which of the following techniques can be used to detect molecules such as proteins in living cells?

A) Fluorescent analog cytochemistry

B) Autoradiography

C) Scanning electron microscopy

D) Transmission electron microscopy

Mass spectrometry is an analytical technique that is used to measure the mass to charge ratio of molecules present in a sample. The sample subjected to mass spectrometry is first ionized to generate parent molecular ions. These ions are then fragmented to produce fragment ions. All the molecules in the sample would then lose an electron and carry a single positive charge. Now all molecules will have the same charge but will differ in their masses which are then measured in mass spectrometry. There are different types of mass spectrometry. Some of them are listed in column I. Match them with their applications in column II.

Immunoprecipitation refers to the technique used to isolate a specific antigen using an antibody. Which of the following statements made regarding immunoprecipitation is incorrect?

Positron emission topography (PET) is an imaging technique primarily used to study organ functioning. In the table given below, radionuclides used in PET are listed in column I. Match them with the applications listed in column II.
