The Human ATRN (Attractin)  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 ATRN. 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 ATRN 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 ATRN, 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 ATRN. You can calculate the concentration of Human ATRN in the samples by comparing the OD of the samples to the standard curve.

The Berkley Flex
Size: 7, Color: Cognac Multi
Very nice shoes, very comfortable, very nice leather. When ordering though, they fit a half size smaller than your size, because they are a tight-fitting shoe.

Better quality than most women’s shoes
Size: 7, Color: Black
I’m a woman and bought these for style and comfort after trying on too many others of multiple price points. These fit well and conformed to my feet after a single wear. Men’s clothes and shoes are so often of better quality.

Well made shoes.
Size: 11.5, Color: Black
Four stars because of the weight. Too heavy for my complete comfort. Also I have a narrow foot (C width) and these are too wide for me. Heavy socks make them wearable but not as comfortable as I would have liked.

Something's changed at Florsheim
Size: 11.5 Wide, Color: Black
I have a pair of size 11W Florsheim Palermo loafers that have lasted over 8 years and are still soft and exceptionally comfortable. Ordered a pair of 11W Florsheim Milano on Amazon but they are too small and have a cheap plastic sole. So, ordered 11.5W Florsheim Berkley and they were way too big. Returned them and ordered 11W Berkley instead and they were also too big ... and the Berkley also has a rubber sole instead of the original leather shown in the product photos. Guess they just don't make them like they used to.
