The Informational Content of Gradients of Wnt Proteins
Science's STKE, 2000This perspective tackles the issues facing developmental biologists and cell biologists regarding how the molecular mechanisms for specifying cell fate are defined. This Perspective focuses on members of the Wnt family. The author proposes that Wnt proteins may act as stabilizing signals for earlier inductive events in certain systems, for

Determination of the phosphate content of purified proteins
Analytical Biochemistry, 1982A technique is described which allows accurate and reproducible determinations of the amount of phosphate that is covalently bound to purified protein. The procedure involves the removal of free or noncovalently bound phosphate, an accurate estimation of the protein concentration of the washed sample, ashing of the sample, and subsequent phosphate ...

Quantification of neuramidase (NA) protein content
Vaccine, 2002An ELISA-immunocapture assay was developed for quantification of influenza neuraminidases (N2 and B), with a sensitivity about 10 ng neuramidase(NA)/ml. This sensitive and specific assay was applied to several trivalent vaccine preparations (1997/1998 and 1998/1999).

The protein content of cerebrospinal fluid in trypanosomiasis
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1948Summary 1. The two common methods of estimation of total protein in the cerebrospinal fluid are the Precipitation (Sicard and Cantaloube) and Turbidometric (Opacity) methods. 2. Experience in the author's laboratory shows that the results given by the Opacity method tend to be one and a half to two times those given by the Precipitation ...

Improving Protein Content and Quality in Legumes
1977Methods suitable for screening protein content in legumes are identified, including dye-binding, infrared (IR) reflectance, air-gap electrode, and micro-Kjeldahl with automatic nitrogen determination. Consideration is given to protein quality, because a smaller content of high-quality protein may be a more desirable breeding objective than a larger ...
