The Human GDF1 (Growth Differentiation Factor 1) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human GDF1. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human GDF1 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human GDF1, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human GDF1. You can calculate the concentration of Human GDF1 in the samples by comparing the OD of the samples to the standard curve.

Amazing Collection!
Format: Hardcover
I've loved Crystal Wilkinson's fiction for so long, so I'm thrilled to see her new book of poems (along with some essays and gorgeous/compelling artwork by Ron Davis). So many memorable image systems work their ways through the poems: creek water, tobacco, the Black body, blood, knives, food and kitchens--symbols and themes which have always marked Wilkinson's oeuvre in one way or another. Her language is lyrical in describing the brutalities of farm life, abuse, grief, and loss. This poetry collection is just stunning!

Amazing Book...
Format: Paperback
It takes a lot nowadays for me to rate any Fiction book 5 stars. I read way more non-fiction, and usually only read highly recommended fiction, or some that's given to me. There are plenty of other reviews here that tell you how it's not a "happy" book (why that matters i dont know), so i wont go on about that part. I dont base my reading choices on whether they have a happy fantasy story. This story is very real. The writing is really good. I have several points that i use to rate a book: the story itself, the actual writing style, the 'entertainment' value, the emotions it brings out - laughter, sadness, etc., and if it's very memorable - either by being very different than anything i've ever read, or by something else about it being very different. The only point out of all of those that i wouldnt give a 5 would be the writing style/prose - which i'd give a 4. It's very good, but not "amazing" to me like some authors are. The author brought me into the characters - where i could feel what they were feeling, and i understood why they did the 'bad' things they did - totally. I felt the way they lived, the area, the poverty... As the story progressed, i stayed up one night for HOURS wanting to know what happened - until the sun rose actually. As the finale was coming - which i had no idea would be the way it was - i was literally gripping the book with both hands and holding it up to my face. I realized this and laughed to myself since i hadnt even noticed. Then - i sobbed thru the last 20 pgs - i havent cried from ANY fiction for a long time. Yes, i get into books and really let them take me away, but this book has a special kind of writing and a special story that i never expected to effect me sooo much. The author THEN does something so amazing at the very end - when i couldnt believe it could get any better. I KNEW what i wanted to happen - and i kept thinking to myself, "no, it wont - because it will just seem to corny if it does." (Even tho i wanted it so much.) She made it happen in a special way, without making it corny but while bringing me the hope and good feeling i needed after all the sobbing. (I dont want to give anything away just in case you dont know the story.) This book scores an A+. If you love good, moving, American fiction you will love this.
