The Human (SDF-1A) Stromal Cell Derived Factor 1A ELISA Kit measures Stromal Cell Derived Factor 1A in samples. The plate has been pre-coated with Human CXCL12 antibody. CXCL12 present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Human CXCL12 Antibody is added and binds to CXCL12 in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated CXCL12 antibody. After incubation unbound Streptavidin-HRP is washed away during a washing step. Substrate solution is then added and color develops in proportion to the amount of Human CXCL12. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm.

Durable
Color: Hammer, Size: 7 Inch
Even my monster hasn't been able to chew through these in a few months, and he has destroyed one of the black Kongs in the same time frame.

Tough to destroy for aggressive chewers
Color: Wrench, Size: 8 Inch
My doggie chewed out stairscase, the sofa, my shoes, and would destroy anything labeled pet “tough” toys. This stopped her from destroying!! Soo cool and cleans her teeth too. I got this one as gift for other retriever fams! Super cool. Doesn’t smell bad and its lightweight but durable like crazy.

Great Toy for Chewers!
Color: Hammer, Size: 7 Inch
This is one of my dog’s favorite toys! He will chew on it for hours. It is durable and takes him a while to make it indistinguishable as a hammer. No smell to it. The rubber bits do come off so I have to check it and make sure he doesn’t eat them.

Good toy
Color: Hammer, Size: 7 Inch
Solid value for the $. The hammer seems particularly good, my bigger dogs like to hold it down by the head. I bought a 2nd.
