The Chicken GTF2F1 (General Transcription Factor IIF, Polypeptide 1) 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 Chicken GTF2F1. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Chicken GTF2F1 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 Chicken GTF2F1, 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 Chicken GTF2F1. You can calculate the concentration of Chicken GTF2F1 in the samples by comparing the OD of the samples to the standard curve.

very poor quality
Size: 14, Color: Black
they are a peice of garbage, within about a month since i started wearing them the outer material started pealing off within two months the upper separated from the soles so i had to go to a shoemaker to sew them back together, within some few months the insoles completely wore out rendering the shoes unwearable, now mind you that i do not abuse shoes but use them in a normal office oriented enviorment, i will for sure not be buying these shoes again

Sleek and classy loafer
Size: 10.5, Color: Black
Was skeptical on this purchase but I have to say, well worth it. Not super expensive but very comfortable. Wears well for summer dress attire for taking your lady out for a dinner or show. Casual yet classy. Not a bad buy.

Great Step In Shoe
Size: 11, Color: Cognac
For people (like me) that have physical and/or medical issues that makes it difficult to bend over to put shoes on, or even to just tie shoes, these shoes make that process so much easier! I have been wearing similar "step in" shoes from another manufacturer (Kizix) that has stopped making leather shoes that are more stylish and business like, similar to this. I haven't tried to polish them yet, but I assume that they will shine up just fine - and they look good now, with a great finish. The sole of the shoe is a solid rubber and I don't slip when I am wearing these, and I am quite impressed by their quality. I look forward to getting another style soon.

Great buy
Color: A-white Flowers Bf290, Size: Large
This shirt is so soft and comfortable. I went with a large, though my recommended size was an xl. I'm so glad that I read the other reviews and went with large, as this is the perfect size for me. Also, with the right color bra, I don't need an undershirt with this. Which is especially nice considering I wanted a nice, light spring/summer top. I also think that it could easily be dressed up or down depending on what it is paired with. Definitely worth the purchase.
