    Fluorescence resonance energy transfer (FRET) polypeptide

    Double fluorescent labeled peptide is also known as FRET (fluorescence energy resonance transfer) peptide. Resonance transfer of fluorescence energy is a kind of energy transfer phenomenon between two fluorescence molecules which are close to each other.

    How to choose proper fluorescent agent for polypeptide

    Fluorescent substance is a compound with the chemical structure of conjugated double bond system. When it is irradiated by ultraviolet or blue violet light, it can be excited into excited state, and when it recovers from excited state to ground state, it

    Basic principles for the design and selection of antigenic peptides

    In order to obtain the best effect of the generated antibody, it is necessary to design the antigen peptide carefully. The design should meet a basic condition: in the immune process, the antigen will not produce too strong immune response, but also can p

    Prediction of acidity and basicity of polypeptide and selection of its dissolving method

    Each acid amino acid was assigned - 1, including aspartic acid (d), glutamic acid (E), and c-terminal-cooh. Each basic amino acid is assigned as + 1, including arginine (R), lysine (k), histidine (H) and n-terminal-nh2. Then calculate the charge number of

    Purity detection, amino acid analysis and theoretical calculation of net content of polypeptide

    The purity of peptide refers to the proportion of target peptide in the sample at the wavelength of 214nm. The sample may contain missing sequence, short segment, incomplete deprotection sequence and so on. The purity of the peptide was obtained by HPLC a

    Synthesis of polypeptide

    Peptide synthesis is a process of adding amino acids repeatedly. The sequence of solid-phase synthesis is generally from C-terminal (carboxyl end) to N-terminal (amino end). In the past, peptide synthesis was carried out in solution, which is called liqui
