Description

QuicKey Pro Human Estradiol ELISA KitThe QuicKey Pro Human Estradiol ELISA kit uses the Competitive ELISA principle. The micro ELISA plate provided in this kit has been pre coated with Human E2. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Human E2 are added to the micro ELISA plate wells. Human E2 in samples (or standards) competes with a fixed amount of E2 on the solid phase supporter for sites on the HRP linked detection antibody specific to E2.

The QuicKey Pro Human Estradiol ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Human E2. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Human E2 are added to the micro ELISA plate wells. Human E2 in samples (or standards) competes with a fixed amount of E2 on the solid phase supporter for sites on the HRP linked detection antibody specific to E2. Excess conjugate and unbound sample or standard are washed from the plate. The substrate solution is added to each well. 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 ±2 nm. The concentration of Human E2 in the samples is then determined by comparing the OD of the samples to the standard curve.

Pretty Good
Color: Red Nylon Yellow Hotdog
The toy is good for a heavy chewer, but is very slippery. You may want to rough it up a bit before giving it to your dog so they can hold onto it.

WARNING - EXTREMELY SHARP AREAS
Color: Yellow Nylon Corn on the Cob, Color: Yellow Nylon Corn on the Cob
UPDATE: The 2nd one I ordered was exactly the same with the sharp parts in the same areas as the first one. I cannot stress enough that a few points are sharp enough to cut or badly scratch. So if you’re planning on putting some food on it so your pup can lick, this is not the product you want! This could still scratch or cut the gums if used as a chew toy too though. I was thinking about sanding the sharp points but then I have no idea if that exposes any chemicals somehow? Really wanted this to work out! I took this corn on the cob toy out of the plastic to wash it and before I even got to the sink I realized there were several areas that are super sharp. A few sharp enough that could cut or badly scratch! It was sealed in a plastic bag and shows no signs of being used so this defect must happen at the manufactures level. I added a video showing how easily it snags a cotton ball, cotton pad and even a beanie. Please thoroughly check your item before giving it to your pup! I was so excited to put some smashed banana on this thing and give it to my guy and thank god I checked it first! I’m going to return it and see if a 2nd one is any better and I’ll update if it is or isn’t. Also, the super sharp spots were very hard to photograph which is why I added the video.
