The Rat BETAEP (Beta-Endorphin) ELISA Kit measures Beta-EP in Rat Serum, Plasma, Cell Culture Supernatant, Cell or Tissue Lysate. This kit is based on Competitive-ELISA detection method and takes 2h assay time. The microplate provided in this kit has been precoated with β-EP. β-EP in the sample or standard competes with a fixed amount of biotin-labeled β-EP for sites on a pre-coated antibody specific to β-EP. Free components are washed off. After adding HRP-Streptavidin Conjugate (SABC), biotin specifically binds with streptavidin to form immune complexes. Wash off unbound conjugate. 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. Compare OD450 value of sample with the standard curve through curve fitting software to determine the concentration of β-EP in the sample. The concentration of the target substance is inversely proportional to the OD450 value.

Work well, no bad skin reactions
Size: 50 count (Pack of 1), Size: 50 count (Pack of 1)
I can't believe what a great deal these are! It's less than $7 (as an add-on buy) for two packets. I had already bought this brand once before so I knew they'd work for me. They remove make-up pretty well. I don't think they are the very best of all time, but they are up there with the other brands I've tried. This product states that it has no artificial dyes or perfumes. These points are really important. Any fragrance that is added to beauty products can irritate your skin, which has happened to me in the past. I do detect the slightest scent, though. It's actually rather pleasant. I think there's still a slight residue of mascara left over after using the wipes pretty thoroughly, so I only gave them 4 stars. Your experience may differ as the packaging promises to remove all makeup residue. Maybe I'm not using them properly? I have very sensitive skin and I didn't break out or otherwise react poorly to these. They do the job as well as I think can be expected for facial wipes so I bought them again. I really hope the claims to being simply formulated are true. I have a healthy scepticism of the beauty industry. My experience with these wipes has been positive so I will take it on faith that they live up to their advertising as far as having no unnecessary additives. One more thing: I like the idea of the added vitamins. It always cracks me up when facial cleansers advertise the addition of helpful vitamins. How can they help when you're immediately rinsing them back off your face? The addition of any vitamins to regular liquid cleansers is just a waste. They do nothing for you. That being said, when they are added to facial wipes, they are spread on your skin and stay there, since you don't generally rinse after using wipes. In this way of cleaning, you may actually be reaping some benefit from the added vitamins.

Indispensable!
Scent: Unscented, Size: 25 Count (Pack of 4)
I love these so much that they are part of my monthly subscribe-and-save program. They have absolutely no scent, which is great, because too many products are over-perfumed. They take off all of my makeup gently. There is no stinging or drying sensation. The cloths are well-sized and the package stays shut when not in use- the cloths do not dry out. After I use a couple of these each night to take my makeup off, I follow up with a gentle, moisturizing facial cleanser. My skin is soft, clean, and happy. I highly recommend these!
