Monoclonal and polyclonal antibodies that bind hamster phospholipase B-like 2 are provided. Also provided are methods for detecting and quantifying hamster phospholipase B-like 2, for example, in recombinant polypeptide preparations, as well as kits for carrying out such methods. Methods of screening or selecting host cell lines or recombinant polypeptide-expressing cell lines that express low levels of hamster phospholipase B-like 2 are also provided.

The invention relates to compositions including polynucleotides encoding polypeptides which have been chemically modified by replacing the uridines with 1-methyl-pseudouridine to improve one or more of the stability and/or clearance in tissues, receptor uptake and/or kinetics, cellular access by the compositions, engagement with translational machinery, mRNA half-life, translation efficiency, immune evasion, protein production capacity, secretion efficiency, accessibility to circulation, protein half-life and/or modulation of a cell's status, function, and/or activity.

Antibodies to the enzyme matriptase-2 (MTP-2) are presented. Inhibiting MTP-2 reduces uptake of dietary iron and reduces the release of iron from cellular stores in the body. Inhibitors of MTP-2 (such as antibodies to the serine protease domain) can be used to treat iron overload, which is a feature of diseases such as beta-thalassaemia and which otherwise leads to toxic accumulation of iron. Combination of an MTP-2 inhibitor with an activin receptor ligand trap, or with erythropoietin, provides additional therapeutic effects.

An object of the present invention is to provide a standard substance for quantification of PSA having a specific sugar chain that can be used in a general purpose quantification, wherein the standard substance has less unbalanced sugar chain expression patterns, can be manufactured with high reproducibility, and enables the quantification of patient's sample comprising a high concentration of PSA, and preparation method therefor, standard solution for PSA quantification, and PSA quantification method. The standard substance comprises a compound having the structure of a PSA with a sugar chain represented by any of the following formulae A to D, and is isolated and purified from a natural product, chemically or enzymatically altered from a natural product, or the compound is artificially synthesized.
