The Human ProCollagen II ELISA Kit measures PCII 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 PCII antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with PCII 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 PCII in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

You can wear them in the water because they are 14 k gold
Love these earrings. They were a little smaller than I thought and the clasp gets wonky after a while.

These have been a conversational piece
Style: 16mm Rose Gold
I thought these were cute. I purchased two sets because I have two holes. They seem like a good quality of rose gold. They are not to big but the heart just hugs my ears.

Deceiving measurements
The earrings are pretty. However, the description shows 2 mm thickness and mine are 1mm (barely). The picture also shows measurements from 16-20 mm which is hard to judge. Mine are 16mm (that’s okay). Lastly but not least, I found the exact same earrings for half the price so now I feel like I over paid for these ones.

Highly deceptive on size, and the packaging is trashy!
Style: 20mm Yellow Gold
A coworker and I purchased these earrings as a gift for another coworker. They arrived today thrown in a plastic bag, with a cheap box that says "LooptyHoops" along with fliers about their other jewelry! The earrings are not ANYWHERE near the size we ordered! I am questioning the legitimacy of this company, and if their earrings are 14K gold!
