Description

Human EGR4 (Early Growth Response Protein 4) ELISA KitThe Human EGR4 (Early Growth Response Protein 4) 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 EGR4. 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 EGR4 and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to

The Human EGR4 (Early Growth Response Protein 4) 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 EGR4. 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 EGR4 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 EGR4, 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 EGR4. You can calculate the concentration of Human EGR4 in the samples by comparing the OD of the samples to the standard curve.

Beautiful shoes
Size: 7 Toddler, Color: Tan, Size: 7 Toddler, Color: Tan
Beautiful dressy shoes! I used to get another version of these for size 6 when my daughter was younger, now she’s getting into size 7, I got her a pair of these. They look great on her and she loves them. Hope they will last a while. The size 6 we had were very worn because she loves them so much that she would pick them over all her other shoes.

Grand daughter likes them, she is 2 1/2 .win win!!
Size: 7 Toddler, Color: Tan
My grand daughter loves these shoes. She is 2 1/2. They are comfortable on her. Her favorite was the white 360 walking shoe but they unfortunately don’t make them in toddler size. (Hint: make them in larger sizes - and why not? ). So I got her these. Stride Rite are good, comfortable shoes for little ones.

Could Be Better
Size: 11 Little Kid, Color: Tan
Look cute for a little while, then the toes peel as shown by other reviewers. It’s such a shame because my four year old LOVES the sparkly stars on the toes. I wish they made a more expensive version in a material that wouldn’t look worn so quickly.

Great boots for fall and winter, but too short for deep snow.
Size: 9 Toddler, Color: Navy
This is the second round of these boots I bought for my kids. They are comfortable for all day at school, like sneakers. Perfect for wet days, feet stay dry and warm. They are not snow boots. We live in Boston and they are not for more than an inch or two of snow. I buy separate true snow boots for snow days (much warmer and taller boots).
