An object of the present invention is to develop and provide a method for conveniently introducing a nucleic acid, a peptide, and/or a low-molecular-weight compound into an empty capsid with viral early infection activities kept. The present invention provides a method for producing a drug delivery particle, comprising the steps of: mixing an empty capsid or an empty particle with a drug including a nucleic acid, a peptide, and/or a low-molecular-weight compound in a solution comprising 0.1 to 20% of a surfactant; and keeping the obtained mixed solution at −5 to 50° C. to introduce the drug into the empty capsid or the empty particle.

This invention relates generally to compositions for making anellovectors and uses thereof. For instance, a method herein can comprise providing a nucleic acid construct that comprises a first Anellovirus genome encoding an exogenous effector and a second Anellovirus genome or fragment thereof, arranged in tandem. In some embodiments, the nucleic acid construct results in production of an anellovector comprising an Anellovirus genetic element encoding the exogenous effector, enclosed in a proteinaceous exterior.

This invention relates generally to anellovectors and compositions and uses thereof.

This invention relates generally to modified anellovirus capsid proteins, anellovectors, anelloVLPs, and compositions and uses thereof.

A method of purifying a sample that includes a desired virus includes the steps of (i) providing a packed chromatographic column having negatively charged porous particles, (ii) equilibrating the column to the conditions to which the desired virus in the sample is to elute, (iii) contacting the sample with the packed chromatographic column such that the sample volume applied to the packed chromatographic column is less than or equal to the interparticle space of the negatively charged porous particles within the packed chromatographic column, (iv) eluting the desired virus from the packed chromatographic column, where the desired virus is in a purer state and in the conditions to which the packed chromatographic column was equilibrated.

The present teachings disclose nucleic acid cassettes for expressing in an insect cell a plurality of polypeptides encoded by a gene comprising overlapping open reading frames (ORFs). A cassette comprises, in 5 to 3 order, a) a first insect cell-operable promoter, b) a 5 portion of a gene comprising a first ORF of the gene, c) an intron comprising a second insect cell-operable promoter, and d) a 3 portion of the gene comprising at least one additional ORF. Vectors and insect cells comprising the cassettes are also disclosed, as well as methods for production of recombinant adeno-associated virus in insect cells using the cassettes.
