Summary Isolation and Characterization of Avian Lactate Dehydrogenase experiment consist of extraction of LDH from chicken breast muscle, then purifying the LDH obtain from chicken breast through affinity column chromatograph, determine protein concentration by Bradford assay and then determining the amount of catalytic activity through activity assays. Through Bradford assays, …

A protein is complex, high molecular-mass, organic compound that consist of amino acids joined by peptide bonds. Proteins are essential to the structure and function of all living cells and viruses. Millon test is given by any compound containing a phenolic hydroxyl group. Consequently, any protein containing tyrosine will give …
