This Stromal Cell Derived Factor 1 ELISA kit uses the Sandwich-ELISA principle
The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm +/- 52 nm
only those wells that contain Mouse SYT1
Then a biotinylated detection antibody specific for Mouse IL-21 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated
and the color intensity is directly proportional to the amount of Human ALK-1 present
Rat F7 (Coagulation Factor 7) ELISA Kit Membrane Attack Complex This Stromal Cell Derived FactorThe Rat (F7) Coagulation Factor 7 ELISA Kit measures Coagulation Factor 7 in Rat samples. The plate has been pre coated with Rat F7 antibody. F7 present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Rat F7 Antibody is added and binds to F7 in the sample. Then Streptavidin HRP is added and binds to the Biotinylated F7 antibody. After incubation unbound Streptavidin HRP is washed away during a washing step.
