Pgem
Could you clarify what Pgem refers to? The term could denote different things in different fields, such as a biotechnology plasmid series (often written as pGEM), a software project, or another concept. If you can specify the intended context (biotech, computing, etc.), I can write a concise, neutral wiki-style article under 300 words. If you meant the Promega plasmid series pGEM, I can tailor the article accordingly.
