The Human GDF1 (Embryonic growth/differentiation factor 1) ELISA Kit measures GDF1 in Human Serum, Plasma, Cell Culture Supernatant, Cell or Tissue Lysate. This kit is based on Double antibody-Sandwich ELISA detection method and takes 4h assay time. The microplate provided in this kit has been precoated with anti GDF1 antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with GDF1 bound to precoated antibody. Wash unbound components and add HRP-Streptavidin Conjugate (SABC). Wash unbound components again and 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. Calculate the concentration of GDF1 in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

It's funny but cheap
My cat does enjoy chasing the little fluff balls around and then batting them for a few seconds than looking back at me for more. It's good for some good laughs and entertainment but the fluff balls and little plastic shooter are honestly dollar tree level quality. The shooter has one flimsy spring and looking at the placement inside it seems like something that'll fall apart pretty fast. Not worth $11 or $8, this should be >$5 easily.

Dangerous
Size: 30 Pcs
My 1 year old cat loved to chase the balls, but who ever designed these balls should be ashamed of their selves. They balls are to small and easy for the cat to chew on and swallow!!! My cat just got done with an extremely costly surgery because he swallowed 3 of the balls he must of hid them somewhere because he usually did not play with them unattended. Never mind the pain my poor sweet baby just went through. I would never purchase something where somebody has not tested the size and shape of something to make sure that it is safe for an animal, sad to assume that somebody would create such a toy without checking that out and putting a animal through this nightmare. This is the first time in my that I have ever done a review, but I would never want somebody to go through what my cat and I have just experienced. Had to him to the emergency room on a Sunday to a follow up appointment at the vet on a Monday and then another follow up appointment on a Tuesday to redo the ultrasound to on Wednesday another appointment to check them and then him having to go in for an emergency surgery on Thursday. The problem is, he didn’t eat them all at one time so they obviously were sitting in his tummy until he started getting sick and throwing up. I will be checking into this company a bit deeper as well, so please be aware and don’t ever purchase something like this.

All 3 cats say 5 stars!
Size: 100 Pcs
The cats love to chase these balls. And it comes with 100! Which is the perfect amount. So far the gun is still working well. I just find you need to barely put the pom pom in after cocking the gun. If you push the pom pom all the way in, it wont shoot. More often than not though, I just throw the balls for the cats. The gun shoots them very far, the cats enjoy chasing them, but they prefer to jump up and try to catch them, which they cant do when I use the gun
