Abstract: Methods and kits for lentiviral production are provided. By separating certain components of the vector including but not limited to promoter, reporter and selection marker preference components from the genetic content of interest, one can create libraries that allow for the efficient generation of custom selected lentiviral vectors.

Abstract: Lentiviral vectors, plates, kits and methods are provided that permit improved efficiency for selection of a promoter sequence for use in a lentiviral application. Through various embodiments of the present invention, a researcher may first evaluate and then choose in a modular fashion, a vector comprising a promoter that is effective for expression in a particular cell line or type.

Abstract: The present disclosure provides a non-naturally occurring miRNA having a stem-loop structure comprising a scaffold derived from a first endogenous miRNA (e.g., miR-196a-2 or miR-204), a mature strand derived from a second endogenous miRNA, and a star strand sequence that is at least partially complementary to the mature strand sequence. The present disclosure also provides a non-naturally occurring miRNA having a stem-loop structure comprising a scaffold derived from an endogenous miRNA (e.g., miR-196a-2 or miR-204), a mature strand designed t be at least partially complementary to a target RNA, and a star strand sequence that is at least partially complementary to the mature strand sequence. The methods and compositions of the disclosure may be used to mediate gene silencing via the RNAi pathway.

Abstract: The present disclosure provides a method of modifying cells in order to enhance lentiviral titers, cell lines that are modified and modifying reagents. By mediating individual genes and combination thereof, lentiviral titers may be increased.

Abstract: Compositions and methods for inhibiting the actions of non-coding RNAs such as miRNAs and piRNAs are provided. The compositions comprise single or double stranded oligonucleotides conjugated with Minor Groove Binders (“MGBs”). The oligonucleotides can vary in length, can contain nucleotides having one or more modifications, and have regions that are substantially complementary to one or more mature miRNAs or piRNAs.

Abstract: The present disclosure provides non-naturally occurring miR-196a-2 miRNAs and non-naturally occurring miR-204 miRNAs. The non-naturally occurring miRNAs of the disclosure have mature strand sequences distinct from their endogenous counterparts. The disclosure also provides methods of selecting mature strand sequences that function optimally in non-naturally occurring miR-196a-2 miRNAs. The methods and compositions of the disclosure may be used to mediate gene silencing via the RNAi pathway.

Abstract: Provided herein are tripartite oligonucleotide complexes which can be administered to a cell, tissue or organism to silence a target gene. The tripartite oligonucleotide complexes of the disclosure may include a conjugate moiety that facilitates delivery to a cell, tissue or organism without the aid of a transfection reagent.

Abstract: The compounds are of class of chromophoric 1,2,3-triazolyl equipped silyl linking groups that are useful in the chemical synthesis of RNA.
