Highresolutionnegativestaining
High resolution negative staining(From Valentine et al, 1968. Biochemistry 7:2143-52)Rationale: For the highest resolution with negative staining, there should be little or no support film, but some support is necessary to hold the protein. In this method the proteins are supported by a carbon film and "embedded" in a film of uranyl acetate. The film is cast on mica, which provides the cleanest possibl......阅读全文
