Rat VIP (Vasoactive Intestinal Peptide) ELISA KitThe Rat VIP (Vasoactive Intestinal Peptide) ELISA kit uses the Competitive ELISA principle. The micro ELISA plate provided in this kit has been pre coated with Rat VIP.

The Rat VIP (Vasoactive Intestinal Peptide) ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Rat VIP. During the reaction, Rat VIP in the sample or standard competes with a fixed amount of Rat VIP on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Rat VIP. Excess conjugate and unbound sample or standard are washed away, and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns from blue to yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of Rat VIP in tested samples can be calculated by comparing the OD of the samples to the standard curve.

Such an Adorable Book
Format: Kindle
This book was one I originally borrowed on Kindle to read to my twin niece and nephew to hopefully help them stop fighting. The book was so adorable, I bought it for Kindle to make sure I always had a copy. While the message is great, treating others with kindness, the illustrations and rhymes are what make it unique. There are some larger words used, but they are all in a clear context to help build vocabulary. The twins loved the farm animals and I actually used the book as part of a lesson on kindness for my Sunday school class who also enjoyed it. Even though I already have the Kindle version, I am ordering paper copies to give as Christmas gifts this year. I love this author, the illustrations, and the message. This is the type of children's book everyone can enjoy and agree on.

A must book for children
Format: Paperback
I got this book 15 years ago at a garage sale and it was one of my kids favorite books of all time. We took it with us everywhere we went (in the car, on vacation etc). My daughter is now in her 20's and she works at a daycare center. She wanted to get some books for their library and when I reminded her of this book she had to get it for them. It has quickly become the classroom favorite, the children ask for her to read it to them daily.
