    • Sample type: Biological fluids (Urine)
      Sample species: Human
      Review: I used this Kit to determine the elastin concentrations on Human urine samples with no dilution in duplicate and obtained %CV values of 0.2-24.4%. All my values were in the detection range, however they were in the lower end of the range. Regarding group differences it is too soon to tell, however I will be purchasing 10 more kits that will allow me to analyse these differences.
    • Sample type: Cell culture supernatant
      Sample species: Human
      Review: The error was not felt between wells of plate, and it was a reliable kit. The box was easy to use and I liked it.
