Whether your protein is simple to produce, or complex and requires more development, in any case, outsourcing your protein expression, purification and production is a very viable option for your projects.
Saving time, resources and money is nearly always a top priority, so calling on outsourcing services to allow you to re-allocate your staff and fund savings makes sense. Particularly given that all the tedious and hard work in optimizing ideal protein expression and purification processes will have already been done for you!
Plasmid preps are to science what salt is to cooking. They’re so common that nobody notices, but nothing can be done without them. There is no mention of this step in any published paper, nobody mentions them in any activity report, no comments are made on how much time is actually spent on it.
But let’s face it: it takes time, as simple and as usual as it may be. A couple of days, spent here and there. It’s so well planned in your weekly agenda, it’s such a habit, that you don’t even think about it. It’s just routine. When you’ve done a plasmid prep a couple of times, there’s nothing new to learn about it. It’s like riding a bike, once you know how, you don’t even notice any more.
