Macromolecule blotting is a process performed after gel electrophoresis. Examples are cellulite localization studies by immunofluorescence or detection by Western blotting. Phycobilisomes can be used in prompt fluorescence, flow cytometry, Western blotting and protein microarrays. Normalization occurs directly on either the gel or the blotting membrane. The gels may also be used for blotting techniques. Using western blotting techniques allows not only detection but also quantitative analysis. This can be useful in subcellular localization, ELISA, western blotting or other immuno-analytical methods. Other techniques used in the analysis of lipid rafts include ELISA, western blotting, and FACS. The purity and amount of protein can be assessed by SDS-PAGE and Western blotting. Waterleaf has low water resistance and includes absorbent papers for blotting. In 1931 Parker created Quink (quick drying ink), which eliminated the need for blotting. It draws moisture through direct contact, often using a blotting or a rubbing motion. Some forms of Lyme disease testing employ western blotting. Unsized paper is blotting paper, making it unsuitable for printing. Milk Makeup began with a lineup of 85 skus including lipsticks and blotting papers.
