Described are affinity purification system that includes a carrier / surface that is non-cellular, and sliding clamp (SC) protein, and methods for purifying proteins that bind to the SC. The SC is associated with the carrier / surface via covalent / non-covalent interactions. To attain control of coupling site, the SC can be mutated via site-directed mutagenesis to introduce an exogenous residue and, the exogenous internal residue is conjugated to the non-cellular surface through the linker. The SC can also be coupled to the carrier via non-covalent interactions such as the affinity interactions involved in ligand / binding partner complex formation.The SC-based affinity purification system are used in a purification column as bait proteins, to isolate SC binding partners or non SC-binding proteins engineered to contain a SC binding site prior to its purification.

The present disclosure relates to methods of coupling antic-cancer agents and anti-cancer treatments to improve the efficacy of the overall treatment. The anti-cancer agent reduces stroma in the tumor microenvironment, in part by killing stroma producing cells such as TAFs and TAMs. Reduction of tumor stroma not only improves immune cell function, including immune cells administered in a second treatment, but also allows allowing other anti-cancer treatments to better access to tumor cells.

The invention relates to expression of the transcription factor Myc and / or pTEF-b and their use as medicaments for inducing proliferation in cells with limited proliferative potential, such as cardiomyocytes. Also described are methods for the prevention and treatment of diseases, such as heart disease, associated with the loss of cells or cell death.

The application provides a PCNA binding protein, a preparation method and application, and relates to the technical field of biology. The PCNA binding protein contains a complementarity determining region of a heavy chain variable region and a complementarity determining region of a light chain variable region, the complementarity determining region of the heavy chain variable region comprises an amino acid sequence identical to VH-CDR1, VH-CDR2 and VH-CDR3 of the heavy chain variable region shown in SEQ ID NO. 1, and the complementarity determining region of the light chain variable region comprises an amino acid sequence identical to VL-CDR1, VL-CDR2 and VL-CDR3 of the light chain variable region shown in SEQ ID NO. 2. The binding protein has good specific binding capacity with PCNA, and can be used for identification of PCNA antibodies or PCNA antigens, and auxiliary diagnosis and detection of PCNA antibody positive diseases.

A quality improving agent for iPS cells that comprises a polynucleotide, said polynucleotide containing H1foo gene and a regulatory sequence.
