HemoCueï£¨ï£¨ ï£¨ Analyzer The equipment used by the ITCA WIC program to test the hemoglobin is called the HemoCue ï£¨ 201+ Photometer. The HemoCue ï£¨ 201+ measures the hemoglobin levels in the blood. Microcuvettes Microcuvettes (also called cuvettes) are the instruments used to collect the blood.
Enzymes Of Yeast. This section is from the book Alcohol, Its Production, Properties, Chemistry, And Industrial Applications, by Charles Simmonds. Also available from Amazon: Alcohol: Its Production, Properties, Chemistry, And Industrial Applications. It is to these important substances that yeast owes its inverting and fermentative properties. They include sucrase (invertase), zymase, maltase (glucase), lactase, hexosephosphatase, reductase, carboxylase, melibiase, and endo-tryptase, as well as proteolytic enzymes, which have already been mentioned in the general description of the enzymes.
Restriction enzymes, also known as restriction endonucleases, are enzymes that cut a DNA molecule at a particular place. They are essential tools for recombinant DNA technology. The enzyme scans a DNA molecule, looking for a particular sequence, usually of four to six nucleotides. Once it finds this recognition sequence, it stops and cuts the strands. This is known as enzyme digestion. On double stranded DNA the recognition sequence is on both strands, but runs in opposite directions.
