High molecular weight polymers, bio molecules or particles in a range of a few nanometers up to several microns are more and more important in science and technology. Many applications are based on the specific properties of these materials. For this reason, an exact knowledge of the molar mass ...
Polyether-modified silicones have a long history of use in the personal care industry as emulsifiers and dispersants, as well as stabilizers for water-in-oil systems. However, because of their external phase type, water-in-oil systems tend to display
The main focus in proteomic studies is on the identification of proteins in given biological samples. Proteins isolated and separated from a given sample (e.g., whole cell lysates, blood or tissue, protein complexes) by immunoprecipitation or affinit
Profiling Using the LightCycler® 480 System
Quantitative real-time PCR (qPCR) has become the de facto standard for nucleic acid quantification. This achievement is due in large part to its sensitivity, specificity, accuracy, large dynamic range of linear quantification, and its speed. The qPCR
Germ-line alterations of the BRCA1 gene confer a lifetime risk of 40% for ovarian cancers and of 40%-80% for breast cancers. It is likely that BRCA1 acts as a tumor suppressor gene. BRCA1 involvement in breast cancers does not seem to be restricted
Mutations in the breast cancer susceptibility gene, BRCA1, occur in the majority of families with multiple members affected with breast or ovarian cancer. Women who inherit a BRCA1 mutation have 40%-80% risk of developing breast cancer or ovarian can
The ability to efficiently introduce foreign molecules into cells constitutes an important tool in any laboratory and facilitates studies of gene regulation and protein function. A plethora of transfection methods have been developed for transfer of
