The Rat IGFBP-4 (Insulin-like growth factor-binding protein 4) ELISA Kit measures IGFBP-4 in Rat 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 IGFBP-4 antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with IGFBP-4 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 IGFBP-4 in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

Poor quality
Size: S, Color: Brown, Size: S, Color: Brown
Hoped that this would be better than it was. The material is cheap and wants to roll in at the zipper making it difficult to close. It does offer lots of room and can be worn as a cross body also.

Professional and streamlined leather backpack
I’ve had a dozen or so backpacks to use for work (corporate environment), and I really love this one. The leather is of high quality, plenty of pockets, strong zippers, straps, and grab handle, and provides a polished, professional, well-put together look. In the rear, zippered compartment, I have a 15-inch HP laptop, an iPad, and a 1/2 inch notebook. The main compartment is spacious and holds chargers for each device plus a lot of other miscellaneous items. There are two front, zippered compartments (one is intentionally “hidden” behind the other) that offer a secure and accessible way to access smaller items like pens, air pods, keys, etc. Great purchase, and I would definitely buy it again.

Love it!!!
Color: Mocha Brown
I bought it because it's the perfect size for carry-on luggage on the plane, and it's big enough to carry several things. Excellent quality for the price. It looks super cute and goes with everything.
