    摘要: The present invention is characterized by a D-aptamer-like peptide (D-Aptide) or retro-inverso Aptide which specifically binds to a target comprising: (a) a structure stabilizing region comprising parallel, antiparallel or parallel and antiparallel D-amino acid strands with interstrand noncovalent bonds; and (b) a target binding region I and a target binding region II comprising randomly selected n and m D-amino acids, respectively, and coupled to both ends of the structure stabilizing region. The D-Aptide or retro-inverso Aptide has the sequence of the same or opposite direction to L-Aptide, wherein the stability to proteases is improved while maintaining the affinity to a target compared with L-Aptide. The D-Aptide of the present invention has substantially the same target affinity and a remarkably improved stability compared with L-Aptide which is different from a general technical knowledge.

    摘要: The present application relates to methods for purifying recombinant proteins, including antibodies and antibody fragments. Suitably, the methods utilize depth filtration to clarify the desired proteins from a solubilized mixture, and provide refolding methods and refolding buffers to allow for refolding of the recombinant proteins into functional and active proteins. Exemplary antibody fragments include anti-CD22 antibody fragments that comprise V H and V L chains refolded into a functional and active fragment.

    摘要: The invention provides methods of preparing macrocycles including macrocycle stabilized peptides (MSPs). Macrocycles and MSPs are prepared according to nucleophilic capture of an iminoquinomethide type intermediate generated from a suitably substituted 2-amino-thiazol-5-yl carbinol. The preferred nucleophile may be selected from an electron rich aromatic moiety in the case of macrocycles and, in the case of MSPs, at least one amino acid comprises an electron rich aromatic moiety. In addition, the concept can be extended to other related 5-membered heterocyclic systems in place of the thiazole, such as imidazole or oxazole. The conditions for the generation of the corresponding iminoquinomethide type intermediates may be similar or different than the conditions used for the 2-amino-thiazol-5-yl carbinol.
