Polyethylene Oxide Standard 160,000

To improve the accuracy and quantitation of bioanalytical methods, you need the proper standard that goes with your desired application. If you’re working with the 160,000-Da protein, then the Polyethylene Oxide Standard is exactly the reference material you need. This specially formulated standard ca be used for molecular weight determination when performing gel permeation chromatography techniques. That way you have a standard to refer back to as you assess the various separations and ensuing data, plus you’ll have a clear way to identify the signal from the internal standard and the signal from your chosen analyte. You can even identify any deleterious effects that may affect your standard and analyte signals negatively by using the Polyethylene Oxide Standard. Add the Polyethylene Oxide Standard to your lab’s toolkit. Or, ask your lab manager to order this essential standard the next time your lab places an order from Waters.

What’s the shelf life of the Polyethylene Oxide Standard?
This standard offers a shelf life of one week after reconstitution and a shelf life of one year normally. Keep this in mind as you perform assays at scale, as you may need to refill this standard shortly after reconstitution. Just make sure to store the Polyethylene Oxide Standard in a fridge that has an internal temperature of four degrees Celsius. Not storing the standard at this temperature may cause shortened shelf life.

If you’re working with gel permeation chromatography and need standards for aqueous molecular weight determination, then we recommend purchasing the Polyethylene Glycol Standards Kit. This kit comes with 10 GPC standards and all have been specially formulated for use with GPC techniques. What’s more, each standard has undergone a strict QC process to ensure optimal chemical purity.
