The present invention provides a method for preparing a bacteriophage displaying an antigen-binding molecule, comprising the step of contacting a helper phage capable of expressing a first polypeptide with a bacterium capable of expressing a second polypeptide, wherein the first polypeptide and the second polypeptide associate with each other to form the antigen-binding molecule.

(Technical problems to be solved) To provide a method for selecting mineral of molybdenum.

(Means for solving the problems) Composition comprising M13 phage for separating a substance containing molybdenum.

A composition can include a carbon nanofiber, wherein a precursor for the carbon nanofiber includes an alcohol and an aldehyde crosslinked by a primary amine. In certain embodiments, the carbon nanofiber can be biotemplated. Biotemplating enables precise control of morphology at the nanometer scale, while molecular templating allows control of carbon nanotexture and structure at the sub-nanometer scale.

The present invention provides a mesothelin binding molecule, comprising an anti-mesothelin single domain antibody. Complementarity determining regions (CDR) of the single domain antibody comprise CDR1 shown in SEQ ID NO: 1, CDR2 shown in SEQ ID NO: 2, and CDR3 shown in SEQ ID NO: 3.

The invention extends to use of the fluorescent compositions and lasing compositions comprising programmable biological substrates in fabricating lasers, and in various biological imaging applications, such as in assays.

The present invention addresses to provide a novel membrane permeability-improving agent which can be applied to high molecular drugs. More specifically, the present invention addresses to provide: a drug carrier which can improve the absorption efficiency of a high molecular drug in the small intestine; and a membrane permeation-improving agent containing the carrier. According to the present invention, a cell membrane-permeating peptide can be provided, which comprises an amino acid sequence selected from the group consisting of the following amino acid sequences: DNPGN (SEQ ID NO: 1); SRPAF (SEQ ID NO: 2); NDPRN (SEQ ID NO: 3); and MSVAN (SEQ ID NO: 4). According to the present invention, a cell membrane-permeable composition can also be provided, which comprises the peptide and a biologically active substance.

The present disclosure relates to a phage-based matrix for inducing stem cell differentiation and a method for preparing the same. More specifically, the present disclosure relates to a composition for inducing differentiation of stem cells, which includes a phage-based matrix in which a gradient of stiffness is controlled by crosslinking a recombinant phage with a polymer, and a method for preparing a phage-based matrix for stem cell differentiation. According to the present invention, the method of the present disclosure provides a physical and mechanical niche environment created by the formation of a nanofibrous structure of the phage whose stiffness is controlled, thereby promoting the differentiation of stem cells into target cells. Therefore, it can be applied to a tissue matrix platform as a variety of conventional tissue engineering materials.

Provided are engineered phages populations, which are homogeneous in length, as well as methods of making and methods of using such phages. Also provided are engineered chlorotoxin -phages as well as their methods of making and using. The disclosed homogeneous phage populations and chlorotoxin-phages may be used, for example, for treating and/or imaging tumors, such as central nervous system tumors.

The present invention relates to vectors suitable for use in displaying proteins on the surface of bacteriophage M13 as fusion constructs with the surface protein P.III, bacteriophage M13 particles comprising a mutated P.III protein on the phage coat surface, as well as methods for producing bacteriophage M13 particles and methods for transfecting or infecting a host cell comprising the vectors and bacteriophage of the invention.

A visual continuous spatial directed evolution method is disclosed. The host grows and moves in a solid culture space, the host carrying a foreign target gene to be evolved and containing a gene element that assists the evolution of the target gene, the target gene being correlated with the growth and movement of the host. Depending on different spatial distribution patterns formed in the solid culture space during the growth and movement of the host, screening is performed to obtain an evolved product. This method is carried out directly in the solid culture space. Depending on images of different spatial distribution morphologies visible to the naked eye that are locally formed, selection of evolved products is performed without the need for liquid fed-batch culture equipment. In addition, the evolution effect is visually observed through the infection spots formed during evolution, so that no real-time monitoring equipment is required.
