Biotin a280
WebThe present invention provides a mutant RSV F protein having a mutation, wherein the mutation is a substitution of a leucine corresponding to a leucine at position 141 of an amino acid sequence of SEQ ID NO: 1 or a leucine corresponding to a leucine at position 142 with a cysteine, and a substitution of a leucine corresponding to a leucine at position 373 with … WebAmine-reactive crosslinker reactive groups. The simplest, most common and versatile techniques for crosslinking or labeling peptides and proteins such as antibodies involve the use of chemical groups that react with primary amines (–NH2). Primary amines exist at the N-terminus of each polypeptide chain and in the side-chain of lysine (Lys, K ...

WebNov 15, 2016 · Answer: It is possible to experimentally determine the molar extinction coefficient (also known as the molar attenuation coefficient) of a protein. You do this by A280 measurements of a dilution series of the protein in known concentrations. A theoretical calculation can also predict an extinction coefficient.
WebThe A 260 /A 280 ratio provides a rapid indication of protein contamination in nucleic acid isolates and less commonly, nucleic acid contamination in protein isolates.
