General description
A convenient and highly reproducible kit for the precipitation and clean-up of proteins. Yield of precipitated proteins is higher than that of traditional methods with improved solubility of the precipitated protein. Contains sufficient components to precipitate 200 samples of ≤200 µl. Requires 150 ml of ethanol (not provided). Kit delivers protein solutions of very low conductivity.
Components
Precipitant 1, Precipitant 2, Precipitant 3, Precipitant 4, Wash Solution, and a user protocol.
Warning
Toxicity: Multiple Toxicity Values, refer to MSDS (O)
Principle
The ProteoExtract Protein Precipitation Kit is designed for the concentration and clean-up of proteins from aqueous samples.
Preparation Note
• Samples: The assay will precipitate proteins from a broad range of sample types containing from 50 µg/ml to 10 mg/ml protein. The assay will tolerate chaotropes (e.g., UREA) to to a concentration of 8 M, detergents up to 4%, and salts up to 2 M.
Note: Prior to using the kit for the first time, the Precipitation Agent and the Wash Solution must be prepared and chilled to -20°C.• Precipitation Agent: 1. To one bottle Precipitant 1 add 1.7 ml Precipitant 2, 1.7 ml Precipitant 3, and 1.7 ml Precipitant 4; mix well.2. The mixture of Precipitant 1, 2, 3, and 4 is called the Precipitation Agent. One bottle Precipitation Agent (34.1ml) is sufficient for precipitation of 40 samples of 200 µl each. 3. Label the Precipitant 1 bottle after reconstitution for easy recognition.• For ease of use, store the Precipitation Agent at -20°C; reconstituted Precipitation Agent is stable for up to 2 months.• Wash Solution:1. Add 150 ml high quality ethanol (not provided) to the bottle of Wash Solution (denatured ethanol may also be used).2. Mix well and store at -20°C. Reconstituted Wash Solutions is stable for up to 1 year.Note: Each 200 µl sample requires 800 µl Precipitation Agent and 1 ml Wash Solution.
Storage and Stability
Upon arrival, all components of the kit can be stored at room temperature (20°C). For ease of use, the prepared Precipitation Agent and the Wash Solution can be stored at -20°C (see Reagent Preparation).
