Loyalty Pays! A Special Thank You from RayBiotech

Get a $5 Gift Card in Every Kit!

RayBiotech Customer Appreciation

In fact, we put this gift card in every individual kit box shipped. For example, our 5 plate ELISA kit comes with a separate box for each plate - That's $25 in gift cards for one order! The $5 gift cards can only be found in kitted products, such as our ELISAs and Arrays. Order today to get one step closer to buying that sweet poster of Justin Bieber!
