Beschreibung
Zusammenfassung:	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.
