The Rabbit TNF-Alpha (Tumor Necrosis Factor Alpha) ELISA Kit measures TNF-Alpha in Rabbit 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 TNF-α antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with TNF-α 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 TNF-α in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

Pleased
My iPad needed an upgrade and I’m pleased with this one. The battery holds 100% charge and the condition is excellent except for some hairline scratches on the back. Overall I’m happy with it and the price was good. I’d recommend this seller any day.

TERRIBLE EXPERIENCE — THE iPAD DOESN’T TURN ON AT ALL
I received an iPad that is completely dead. It doesn’t turn on at all, no matter what I try. I tested it with different chargers and adapters — nothing works. There’s no charging sign, no Apple logo, no reaction whatsoever. It’s just a dead device, clearly defective. On top of that, the color is wrong. I ordered silver, but they sent me blue, which looks totally different from the pictures — it’s more like a dull gray tone. I live in Armenia, and returning the product from here is extremely difficult and expensive, so I’m basically stuck with a non-working iPad that I can’t even use. The whole situation is very disappointing — the product is not as described, it’s faulty, and the seller provides no proper help or responsibility. Do not buy from this seller. The item was dead on arrival, the color was wrong, and the support was useless. If you value your money and peace of mind, avoid this seller completely.

Excelente pero mal en embalaje y cable
Excelente compra, la verdad esta como nueva, parece recien comprada de la tienda oficial pero el embalaje deja mucho que desear, perfectamente se pudo haber dañado pero no, y bueno otra cosa es que demasiado mala calidad de cable y cargador, minimo un cable genuino hubiesen puesto pero por dicha ese no es un gran problema.

Is this really refurbished? Practically brand new
Practically brand new. Only difference is the charger/cable are third party and no apple box. I can forgo the Apple unboxing to save a few dollars.
