Compositions and methods for the storage, organization, access, and retrieval of information encoded by sequence controlled polymers such as data storage nucleic acids are provided. In some embodiments, organization, storage, and/or selective retrieval of the data is facilitated by hybridization of barcode sequence of the sequence controlled polymer to the reverse complementary sequence of an oligonucleotide. The plurality of oligonucleotides can be arrayed using a known organization scheme, and selectively capture and localize the corresponding sequence controlled polymer. In some embodiments, the compositions and methods utilize recombinant bacteriophage, typically featuring a minigenome having a bacteriophage origin of replication and packaging signal separated from a data storage sequence by barcodes.

Methods and compositions for bacterial production of pure single-stranded DNA (ssDNA) composed of custom sequence and size have been developed. The methods enable scalability and bio-orthogonality in applications of scaffolded DNA origami, offering one-step purification of large quantities of pure ssDNA amendable for immediate folding of DNA nanoparticles. The methods produce pure ssDNA directly from bacteria. In some embodiments the E. coli helper strain M13cp combined with a phagemid carrying only an f1 -origin allows for, without the need for additional purification from contaminating dsDNA. This system is useful for generalized circular ssDNA synthesis, and here is applied to the assembly of DNA nanoparticles folded both in vitro and direct from phage.

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 invention relates to agents and to pharmaceutical compositions for reducing the formation of amyloid and/or for promoting the disaggregation of an proteins. The compositions may also be used to detect amyloid.

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.

The invention relates to polypeptides that comprise a portion of filamentous bacteriophage gene 3 protein (g3p) sufficient to bind to and/or disaggregate amyloid, e.g., the N1-N2 portion of g3p and mutants and fragments thereof, wherein that g3p amino acid sequence has been modified through amino acid substitution to be substantially less immunogenic than the corresponding wild-type g3p amino acid sequence when used in vivo. The polypeptides of the invention retain their ability bind to and/or disaggregate amyloid. The invention relates furthermore to the use of these variant g3p-polypeptides in the treatment and/or prevention of diseases associated with misfolding or aggregation of amyloid.

Disclosed herein are novel synthetic bacteriophages and bacteriophage compositions, methods of production thereof, and therapeutic uses thereof.
