Foreword

Evaluating hypotheses and making judgements on the basis of well supported evidence solve problems in science. Medical and biological data mainly consist of measurement of assay conditions to support the proposed hypothesis. A prediction must test variables and scientist must acquire data from experiments to elicit an explanation or description to the scientific problem. Experimental results of the assay provide direct or indirect evidence to the theory. Therefore, several techniques have been developed to help researchers facilitate experimental design and to elucidate molecular mechanism of biological systems. Some techniques alone may provide unique evidence while still other complement other techniques. For this reason, investigators must be informed about the techniques and know them in detail. It is hard to follow up each technique specially for early career scientists and its applications for experienced researchers. The first volume of this book provides a training platform and application modules of each technique and may help individual investigators to guide research practices.
