Great product, works great. Our normal vendor was backordered for 2 months, got excellent customer service from Hello bio. Product worked great and delivery was fast.  But best of all the price was great and we saved enough to buy other needed laboratory essentials. Researcher, University of Texas Health Science Center at San Antonio, USA

The product worked well. We were using Sigma but went to you for availability and pricing. It works the same and we will be using your products for now on. This is used in the lab frequently and our concern was the quality but you do a fine job with this. Researcher, Washington University in St Louis, USA

Excellent. We achieved excellent recombination using this product on our cre-lox mouse cross.  This product also had the best price found across vendors. Researcher, University of Calgary, Canada
