Provided are compositions and methods for treatment of tumors. The compositions comprises a fusion construct comprising single domain antibody (sdAb) that is specific for HER2, collagenase, and optionally, albumin binding domain. Methods are provided for increasing penetrability of tumors and inhibiting the growth of tumors comprising administering a fusion construct comprising anti-HER2 specific sdAb, collagenase, and optionally albumin binding domain, alone or in combination with and an anti-tumor agent.

Products, compositions, and their uses are provided. In particular, nucleic acid products that modulate, in particular interfere with or inhibit, Factor XI (FXI) gene expression are provided. The products can be oligomeric compounds that comprise at least a first region of linked nucleosides having at least a first nucleobase sequence that is at least partially complementary to at least a portion of RNA transcribed from an FXI gene, wherein said first nucleobase sequence is selected from the following sequences, or a portion thereof: SEQ ID NOs 1 to 250.

Described are compositions, in particular lyophilizates, containing proteolytic enzymes, and methods for producing the compositions. Typically these compositions contain one or more proteases with collagenase activity and a neutral protease, for example, thermolysin. The compositions are free of acetate salts. Surprisingly, such compositions can be dissolved in water more rapidly than lyophilized protease mixtures of the state of the art.

The disclosure relates to an expression method of a Haemocoagulase Acutus (Halase) recombinant protein. The method includes the following steps: (1) optimizing a halase gene; (2) performing Polymerase Chain Reaction (PCR) amplification on an optimized halase gene; (3) constructing an Agkis-pMCX expression vector, transforming plasmids to competent cells of an Escherichia coli for amplification, screening in an Amp-resistant manner for positive cloning, sequencing and extracting recombinant plasmids with correct sequencing; (4) transfecting recombinant plasmids to CHO cells; and (5) expressing the recombinant protein and identifying. According to the expression method, a recombinant halase is expressed first using the CHO cells cultured in a serum-free suspension manner; and by utilizing a bioengineering means, the actual production problems of insufficient raw material sources and unstable quality of a snake venom product are solved successfully.

The present disclosure relates to solutions and methods of preparing lyophilized formulations of factor Xa (fXa) antidotes. A suitable aqueous formulation suitable for lyophilization can include a fXa antidote, a solubilizing agent, and a stabilizer, wherein the formulation does not collapse during lyophilization.

The invention relates to modified Factor IX coding sequence, expression cassette, vectors such as viral (e.g., lenti- or adeno-associated viral) vectors, and gene transfer methods and uses. In particular, to target Factor IX nucleic acid to cells, tissues or organs for expression (transcription) of Factor IX.

The present invention relates to the field of biochemistry, more particularly to proteomics, more particularly to protein sequencing, even more particularly to single molecule peptide sequencing. The invention discloses methods for single molecule protein sequencing and/or amino acid identification using cleavage inducing agents which are not specific for one particular amino acid, cleave polypeptides step by step from the N-terminus onwards and provide information on the identity of the cleaved amino acids based on the reaction kinetics.

Provided herein are methods for evaluating tumor cell spheroids in a three-dimensional microfluidic device by determining changes in the relative levels of live cells and dead cells in aliquots cultured under different conditions. Methods described herein allow ex vivo recapitulation of the tumor microenvironment such that the in vivo effectiveness of a test compound in treating tumor tissue may be predicted.

The present invention relates to anti-MASP-2 inhibitory antibodies and compositions comprising such antibodies for use in inhibiting the adverse effects of MASP-2 dependent complement activation.

Non-human animals, tissues, cells, and genetic material are provided that comprise a modification of an endogenous non-human heavy chain immunoglobulin sequence and that comprise an ADAM6 activity functional in a mouse, wherein the non-human animals express a human immunoglobulin heavy chain variable domain and a cognate human immunoglobulin λ light chain variable domain.
