Supplier: Ahlstrom-Munksjö

Ahlstrom-Munksjö’s qualitative grades of filter paper are recommended for use in analytical methods which determine or identify particulate constituents of a mixture irrespective of the amount present. Qualitative filter papers are often used in routine separation work that still requires high purity and consistent performance. These filter papers covers a wide range of laboratory applications, as liquids clarification, qualitative analytical separations for precipitates and buffers filtration, and are also used for soil analysis and in food and beverage testing. Wet-strengthened grades contain a reinforcement agent that increases their resistance to rupture when wet, such as in vacuum filtration, and their resistance when filtering acidic solutions.

Protein Phosphatase 1G (PP1MG) is a cytoplasmic protein that belongs to the PP2C family. PPM1G is widely expressed; it is abundant in testis, skeletal muscle, and heart. PPM1G is a negative regulator of cell stress response pathways. PPM1G is responsible for the dephosphorylation of Pre-mRNA splicing factors, an important factor for the formation of functional spliceosome. PPM1G also plays a role in regulating cell cycle progression.

DENARASE High Salt is an engineered version of the wild-type Serratia marcescens endonuclease, which is commonly used for DNA removal applications in bioprocessing. Compared to the wild-type DENARASE, a few amino acids were substituted to provide the enzyme with an improved salt tolerance without losing its specificity for nucleic acids.

Supplier: Biotium

Ethidium monoazide bromide (EMA) is a fluorescent nucleic acid stain with a photoaffinity label. The dye, after photolysis, binds covalently to nucleic acids. The dye has been used to footprint drug binding sites on DNA, to modify plasmid DNA, and for labeling yeast cells for leukocyte phagocytosis assays.

Supplier: MP Biomedicals

Dissolve at a concentration of 1 mg/ml. Dilute further to a concentration of 20 to 60 U/ml immediately before the assay.

Supplier: Thermo Fisher Scientific

This purified calf intestinal alkaline phosphatase (CIP) is supplied in Tris buffer and 50% glycerol for use in protein research methods. The main applications for alkaline phosphatase in molecular biology and protein research are to remove 5'-phosphate groups from DNA or as a reporter system for immunoassays such as ELISA. For these latter methods, the enzyme is usually conjugated to specific primary or secondary antibodies and its activity is detected with a color-forming (or light-generating) substrate.

Supplier: HyClone products (Cytiva)

Minimum Essential Medium (MEM) is one of the earliest modifications of Basal Medium Eagle (BME) containing amino acid concentrations that more closely mimic those found in mammalian cells. MEM has been used with serum supplementation on a broad range of cell types including suspension and adherent mammalian cells, HeLa, BHK-21, HEK-293, HEp-2, HT-1080, MCF-7,fibroblasts and primary rat astrocytes.

Taq DNA Polymerase is a highly thermostable DNA polymerase from the thermophilic bacterium Thermus aquaticus. The enzyme catalyses 5'→3' synthesis of DNA, has no detectable 3'→5' exonuclease (proofreading) activity and possesses low 5'→3' exonuclease activity. In addition, Taq DNA polymerase exhibits deoxynucleotidyl transferase activity, which frequently results in the addition of extra adenines at the 3'-end of PCR products. Recombinant Taq DNA Polymerase is ideal for standard PCR of templates 5 kb or shorter.

The enzyme catalyses 5'→3' synthesis of DNA, has no detectable 3'→5' exonuclease (proofreading) activity and possesses low 5'→3' exonuclease activity. In addition, Taq DNA polymerase exhibits deoxynucleotidyl transferase activity, which frequently results in the addition of extra adenines at the 3’-end of PCR products. Native Taq DNA polymerase is preferred for amplification of bacterial DNA sequences homologous to those found in E.coli.

Coronary heart disease and stroke are major causes of death in the Western world. Elevated blood cholesterol levels are a serious risk factor in both conditions. The genetic disease familial hypersholesterolemia (FH) causes an increase in blood levels of the bad form of cholesterol, low density lipoprotein (LDL). In untreated patients with the mutant FH gene, the condition can cause premature death. This experiment introduces the colorimetric enzymatic reaction which is the basis of the clinical cholesterol test. In addition, using agarose gel electrophoresis, students can analyse a simulated genetic screening for a disease.
