Description

Human TPH1 (Tryptophan Hydroxylase 1) ELISA KitThe Human TPH1 (Tryptophan Hydroxylase 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 Human TPH1. 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 TPH1 and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to each micro

The Human TPH1 (Tryptophan Hydroxylase 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 Human TPH1. 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 TPH1 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 TPH1, 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 TPH1. You can calculate the concentration of Human TPH1 in the samples by comparing the OD of the samples to the standard curve.

Really like these cotton rounds
Size: 100 Count (Pack of 1)
I do like these cotton rounds. They hold up and work well to remove make up and clean my skin in between actually washing my face. They are soft but strong and a good size for makeup removal. These are much nicer than the ones I bought previously that shed on my skin. They are somewhat thick and seem to have a decent cotton content.

Sky High is right!
Color: BLACKEST BLACK, Size: 0.24 Fl Oz (Pack of 1)
This mascara truly delivers. The formula dries quickly without flaking or transferring, and the slim applicator brush makes application effortless and precise. I wore it all day and well into the night, and it stayed flawless the entire time with no touch-ups needed. Long-lasting, lightweight, and high quality. I will definitely be repurchasing.

Great mascara
Color: BLACKEST BLACK, Size: 0.24 Fl Oz (Pack of 1)
I’ve tried a ton of mascaras but this one definitely far exceeds my expectations compared to other mascaras. I wouldn’t go as far as to say your lashes will be unbelievably long and fake looking- but it definitely adds volume and depth to my lashes while maintaining a real lash look. I don’t have issues with clumping or lash breakage with this mascara. It washes off easily without leaving you with raccoon eyes. Also it does not cause eye sensitivity for me.
