Provided herein are protein-based purification matrices and methods of use thereof to purify biologics and/or to remove contaminants from a composition. Methods of bringing two or more biologics in close proximity are also provided. The disclosed compositions and methods allow for faster, more efficient purification of a biologic compared to traditional affinity chromatography.

The present invention provides caninized human anti-human IL-4Rα antibodies that have specific sequences and a high binding affinity for canine IL-4Rα. The invention also relates to use of these antibodies in the treatment of dogs against atopic dermatitis.

The invention is directed to a system comprising a lentivirus vector particle which encodes at least one guide RNA sequence that is complementary to a first DNA sequence in a host cell genome, a Cas9 protein, and optionally a donor nucleic acid molecule comprising a second DNA sequence. The invention also is directed to a method of altering a DNA sequence in a host cell using such a system, where the host cell can be in a human and the altered DNA can be of the human β-globin gene. The invention also is directed to a fusion protein comprising a Cas9 protein and a cyclophilin A (CypA) protein. The invention also is directed to sequences of vectors that can be used in the system and method.

The subject invention pertains to materials and methods for detecting, preventing and treating retroviral infections in humans and other animals susceptible to infection by retrovirus. It has been discovered that FIV can be transmitted from cats to humans and that the FIV can infect human cells in vivo and that antibodies generated by the infected person cross-react with HIV antigens. Thus, the methods and compositions of the subject invention can be used to detect, prevent and treat FIV infection in humans and other non-feline animals that are susceptible to FIV infection. The methods and compositions of the invention can also be used to prevent and treat infection by HIV in humans.
