Description

Rat T4 (Thyroxine) ELISA KitThe Rat T4 (Thyroxine) ELISA Kit measures T4 in Rat Serum, Plasma, Cell Culture Supernatant, Cell or Tissue Lysate. This kit is based on Competitive ELISA detection method and takes 2h assay time. The microplate provided in this kit has been precoated with T4. T4 in the sample or standard competes with a fixed amount of biotin labeled T4 for sites on a pre coated antibody specific to T4. Free components are washed off. After adding HRP Streptavidin

The Rat T4 (Thyroxine) ELISA Kit measures T4 in Rat Serum, Plasma, Cell Culture Supernatant, Cell or Tissue Lysate. This kit is based on Competitive-ELISA detection method and takes 2h assay time. The microplate provided in this kit has been precoated with T4. T4 in the sample or standard competes with a fixed amount of biotin-labeled T4 for sites on a pre-coated antibody specific to T4. Free components are washed off. After adding HRP-Streptavidin Conjugate (SABC), biotin specifically binds with streptavidin to form immune complexes. Wash off unbound conjugate. Add TMB substrate solution. Then, TMB was catalyzed by HRP to produce a blue color product that turned yellow after adding a stop solution. Read the O.D. absorbance at 450nm in a microplate reader. Compare OD450 value of sample with the standard curve through curve fitting software to determine the concentration of T4 in the sample. The concentration of the target substance is inversely proportional to the OD450 value.

Good quality, lotsa fun
Size: Basketball
I wanted to train my dog to shoot basketball but he loves this ball so much as a toy that I had to find something else for the basketball game and let him play as much as he wants with this one

Smaller than expected

My dog likes it; but I thought it was going to be bigger than it is. It is the blue ball pictured on the right compared to a normal size soccer ball on the left.

My dog’s favorite toy and mine!
Size: Basketball
My Min Pin loves this ball! It’s durable, chewable and (my favorite) toss able in the house! Since it’s soft, it doesn’t make noise when it bounces across the floor or hits a wall or the door. Best indoor throw toy ever!

Puppy loves it! We have had hours of fun with it.
Size: Billiards
My puppy loves it! It’s soft, squishy and squeaks. I would have given 5 stars but some threads on the 8 started to come out (not completely) after a few days, but it still seems well made and we have had had many hours of fun with it.
