As much as your science depends on knowledge, skills and experience, the results that you get from your experiments will also be determined by the quality of products that you use. If X Gal is one of those products you need to be extra careful when selecting a supplier – with so many of them masquerading as such these days you may end up with the wrong product which will negatively skew your experiments. Before you contract an X Gal supplier make sure that they meet the following qualifications:
• They should have been in the industry long enough to have established a good reputation for themselves. A lot of supplies who supply unreliable products fall under the fly-by-night category – they are here one minute and gone the next. The longer the supplier has been around the more reliable you can expect them to be.
• Make sure that the supplier is using the latest science to develop their products. They should also have invested in the latest equipment. Do not take their word for it – ask them to take you on a tour of their factory so that you can see their processes and equipment.
• Is the supplier willing to provide you with X Gal in the long term? The last thing you want is to be looking for a new supplier in a few months or a few years. A good supplier is one who comes on as a partner – they are willing to work with you for as long as you need them.
• It is best to choose a supplier who can supply you not just with X Gal but also with products that you need for other experiments. Find out what a supplier’s range of products is before you contract them.
