Description

Human PRSS33 (Protease, Serine 33) ELISA KitThe Human PRSS33 (Protease, Serine 33) 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 PRSS33. 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 PRSS33 and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to each

The Human PRSS33 (Protease, Serine 33) 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 PRSS33. 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 PRSS33 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 PRSS33, 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 PRSS33. You can calculate the concentration of Human PRSS33 in the samples by comparing the OD of the samples to the standard curve.

Pretty. Tiny. Hopefully has good battery life. UPDATE: The silver one was defective.
Color: Gold Raquel, Size: 14MM, Color: Gold Raquel, Size: 14MM
I bought both the gold and the silver ones. I have a collection of ring watches but most of them are sets you can buy for cheap. These are my first made by a well known watch company. They look big on picture but they are tiny. I bought it so when my smartwatch dies I have one on my ring to tell the time. I don't like going on my phone to check the time just to avoid distractions. I hope the battery lasts long. Updated review: I started using the gold one and it works great! The silver one wasn't working so I processed a return for it. However when they shipped the replacement, there was nothing inside the tin can fossil case. I called Amazon and they refunded me for the silver one. The product works great. I probably got a defective one. My fear is maybe someone took the ring before packing it for replacement. That's just wrong. I'm going to get the silver one from Macy's instead.

Cheaply made
Color: Gold Glitz, Size: 15MM
I really love the concept and honestly it’s super cute BUT the diamond around the face of the watch fell off within the first wear:/ so unfortunate because it has so much potential.

Beautiful watch, great packaging, but didn’t work.
Color: Silver, Size: 15MM
I love my ring watch so much that this is my second one (I washed my first one 😩). I ordered the ring on Wednesday and I got it Friday. I was so happy to get it, great packaging and fast delivery imagine how hurt I was when it didn’t work. I am gonna try to get a new battery and I pray that works but with the price being 80 plus dollars this should have never been a problem.

Need more in different styles!
Color: Gold Glitz, Size: 15MM, Color: Gold Glitz, Size: 15MM
This ring watch is perfect! The face on it isn’t as big as all the other ring watches; which is why I chose it! I wanted something more dainty, as I have small fingers and hands. This ring is shiny, and the little crystals sparkle so nicely! The band doesn’t pinch, and I can wear it on multiple fingers. Easy to set and has kept time so far. Would recommend!
