The SPX (Spexin) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human SPX. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human SPX. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human SPX, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human SPX in the samples is then determined by comparing the OD of the samples to the standard curve.

Adorable Fathers Day book!
Format: Board book
I got this book for my husband for Father’s Day, and it’s absolutely adorable. The message is sweet and heartfelt, focusing on how Dad supports, plays with, and loves his child. The writing has a lovely, warm tone that’s perfect for reading aloud together. The book itself is also excellent quality — it has a thick padded cover and sturdy board book pages that can withstand little hands. The illustrations are vibrant with great color contrast, which keeps our toddler engaged. Highly recommend as a gift or a bedtime staple for any dad and child duo!

Cutest little story!
Format: Board book
I just got this for my son and his Daddy. The story is so cute and I may have gotten choked up at the end. If you’re looking for a story for your man to read to your little one(s), I highly recommend this one!

Lovely, adorable & well-written - perfect, "daddy" book!
Format: Board book
I bought this book for my son (and maybe a little for my husband lol) when I realized he had 3 "mommy-centered" books, but none for daddy. I wanted one with quality artwork that also had a more tender and meaningful approach, rather than just silly, one that could foster appreciation of my husband and how much he loves my son. I had a difficult time narrowing down which book to get, but I am SO very glad that this is the one I went with. The pictures are adorable, the rhythm & rhyming are very well done and flow well, and the message of the book is exactly what I was hoping for, showing how daddy helps baby learn and grow and how much they love each other. My son loves it!
