The QuicKey Pro Sheep Cortisol ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Sheep Cortisol. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Sheep Cortisol are added to the micro ELISA plate wells. Sheep Cortisol in samples (or standards) competes with a fixed amount of Cortisol on the solid phase supporter for sites on the HRP linked detection antibody specific to Cortisol. 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 Sheep Cortisol in the samples is then determined by comparing the OD of the samples to the standard curve.

They’re fantastic!!!!
Size: X-Large, Color: Multicoloured E-(5-pack)
My clothing size is 16/18 and XL. Even though Amazon suggested a size XXL, I ordered my normal XL and they fit perfectly. The fabric for this style is 92% bamboo viscose and is amazingly soft and almost silky feeling. I had ordered a different boy short in this brand but they were 80% bamboo viscose and the fabric was significantly heavier. I returned those and ordered these.

Genuinely comfortable and practical for everyday wear
Color: A-5pack, Size: Large, Color: A-5pack, Size: Large
I am very impressed with the FINETOO Boyshort Underwear for Women. These are extremely comfortable, even after wearing them all day. The cotton material is soft, breathable, and feels great against the skin without causing irritation. The cut is well designed and offers full coverage that stays in place without riding up. They are very wearable for everyday use, whether lounging, working, or running errands. I also appreciate that they do not create noticeable panty lines, which makes them easy to wear under different types of clothing, including leggings and jeans. Durability has been excellent so far. I have washed them multiple times, and they have not shown any signs of wear, stretching, or fading. The stitching has held up well, and the fabric still feels just as comfortable as when they were new. The color variety in the pack is another plus. The colors are cute, practical, and easy to mix into a regular underwear rotation. Overall, these boyshorts check all the boxes for comfort, durability, and everyday wearability. I would definitely recommend them to anyone looking for reliable, full coverage cotton underwear. A few are missing from my screenshot as I had already worn them!

Made with quality
Color: A-5pack, Size: Small
I ordered a pack of these sometime last year and they have lasted. They r made with quality stitching & the material isnt smothering. These ain’t gonna make your cat stank on a hot day, they r breathable. Sorry didn’t know how else to get that point across. But I just ordered 2 more packs. They r aslo comfortable and don’t feel tight, smothering, or itchy. The material is very comfortable against my skin. The tag is on the left, so when u hold them up u can tell which side is the front and back. They cover enough & form to your body so they r also cute and flattering. They do leave some cheek exposed, for me anyway. These also don’t bunch up & cause wedgies. They stay in place. I have a physical job so I move around a lot, & clean house a lot, & these don’t move around at all. Small fits me perfectly & they do stretch. I’m petite but curvy. I wear cotton leggings & layers frequently, for my job in a cold room, and you can’t c these panty lines thru the cotton leggings. These r also kinda low cut, and they sit below my belly button. These ain’t gonna hold in a fupa or anything, but they do compliment natural curves. I’d leave a pic but not for free 😉

Underwear for sensitive, soft and comfortable skin
Color: A-5pack, Size: Small, Color: A-5pack, Size: Small
I really like them for their soft fabric and comfort, I washed them and I thought they were going to get bigger, but they were left intact, they are made with cotton I am of sensitive skin and it worked for. I asked for others of the same brand, but they are different style, they are beautiful they are not rolled up. size S.

Good value
Color: C-5pack, Size: Large
These are good panties for the price but I don't love that they don't have a tag or something printed to know which is the back and front. You can tell once you put them on but that's a bit annoying when you get it wrong. Not a super big deal though. They are comfortable and pretty true to size. They look just as pictured. Definitely worth the price that I paid and I would buy them again. Very lightweight and comfortable
