Patents by Inventor Frank Buchholz

Frank Buchholz has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11845954
    Abstract: The invention provides methods for specifically altering the DNA sequence in a genome, in particular for genome editing by deleting or replacing a sequence of interest. Advantageously, the invention uses two non-identical sequences naturally occurring in a genome as target sites two which DNA-recombining enzymes are generated. The invention is in particular useful for medicine, in particular to repair a mutation in a genome or to delete predefined genetic material from cells or tissue and to cure diseases. An advantage of the invention is that it allows precise site directed altering of DNA without engaging host DNA repair pathways and thereby works without inducing random insertions and deletions (indels).

  • Patent number: 10316301
    Abstract: The present invention relates to a method for preparing an expression vector encoding a tailored recombinase, which tailored recombinase is capable of recombining asymmetric target sequences within the long terminal repeat (LTR) of proviral DNA of a plurality of retrovirus strains inserted into the genome of a host cell, as well as to the obtained expression vector, cells transfected with this, expressed recombinase and pharmaceutical compositions comprising the expression vector, cells and/or recombinase. Pharmaceutical compositions are useful, e.g., in treatment and/or prevention of retrovirus infection. In particular, asymmetric target sequences present in a plurality of HIV strains are disclosed, as well as tailored recombinases capable of combining these sequences (Tre 3.0 and 4.0) and expression vectors encoding them.

  • Patent number: 10253332
    Abstract: The invention relates to the use of a protein with recombinase activity to catalyze a site-specific DNA recombination and a method for producing a site-specific DNA recombination. The invention is applicable alone or in combination with other recombinase systems for genetic manipulation, for example in medical research. The objective of the invention is solved by the use of a protein with recombinase activity to catalyze a site-specific DNA recombination at, preferably at two, recognition sites that are identical or reverse complementary to each other. The invention also includes a method for producing a site-specific DNA recombination comprising the steps of a) providing a cell comprising at least two recognition sites that are identical or reverse complementary to each other; and b) contacting a protein with recombinase activity with the recognition sites, thereby producing the site-specific DNA-recombination.

  • Patent number: 10150953
    Abstract: The present invention relates to a method for preparing an expression vector encoding a well-tolerated and highly specific tailored recombinase, which tailored recombinase is capable of recombining asymmetric target sequences within the long terminal repeat (LTR) of proviral DNA of a plurality of retrovirus strains which may be inserted into the genome of a host cell, as well as to the obtained expression vector, cells transfected with these, expressed recombinase and pharmaceutical compositions comprising the expression vector, cells and/or recombinase. Pharmaceutical compositions are useful, e.g., in treatment and/or prevention of retrovirus infection, in particular, HIV infection. In particular, the invention relates to well-tolerated and highly specific tailored recombinases capable of combining asymmetric target sequences in a more than 90% of HIV-strains, thereby excising the HIV-1 sequences, and expression vectors encoding them.

  • Patent number: 8819155
    Abstract: Methods, systems, and apparatuses for processing function calls using a hooking routines to perform pre-execution tasks are disclosed. A server computer receives a function call including a hooking routine and a request to run a particular function from a client computer. Based on a function group identifier and the credentials of the user or client computer, the server computer can perform various pre-execution tasks. The tasks can be common to all functions in the function group or be customized Both pre-execution tasks can be stored remotely from the client computer, so that updates to the pre-execution task can be made without the need to update computer readable code stored on the client computer. If the pre-execution tasks, such as an authorization, passes, then the server computer can execute the requested function, the server computer can reject or abort the requested function.
