The Guinea pig TNFRSF1A (Tumor Necrosis Factor Receptor Superfamily, Member 1A) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Guinea pig TNFRSF1A. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Guinea pig TNFRSF1A and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Guinea pig TNFRSF1A, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Guinea pig TNFRSF1A. You can calculate the concentration of Guinea pig TNFRSF1A in the samples by comparing the OD of the samples to the standard curve.

Quiet, Powerful, and Reliable — The Best Grinder Set We’ve Owned
Material Type: Updated-Stainless Steel
After going through several cheaper grinder sets that never held a charge, struggled to grind properly, and eventually broke, I decided to invest in a higher-quality set. This one seemed to check all the boxes — sleek design, convenient charging stand, and an overall premium look — so we decided to give it a try. From the moment we charged them up, filled them with our favorite salt and pepper, and started using them, the difference was night and day. The grind adjustment is impressively versatile, ranging from coarse to very fine, and it’s much easier to adjust than on our old grinders. The charging base uses a USB-C connection, which is a big plus — it works with the same chargers we use for our phones. Aside from the initial charge, we’ve only had to recharge them once in more than six weeks of regular use. The grind quality is excellent, the operation is smooth and quiet, and they don’t sound like they’re straining like our previous sets did. If you’ve been disappointed by cheap electric grinders in the past, do yourself a favor and upgrade to this set. It looks great, performs flawlessly, and is absolutely worth the investment.

Very nice grinders!
Material Type: Updated-Stainless Steel
Really nice grinders. I love all of the options for the size of the grind you need, very easy to adjust. They look really nice in the kitchen and Mach my other stainless steel items so that’s a big plus. They hold a lot of salt and pepper as well. The batteries last a nice long time too, and they don’t take long to charge. Functions just as they should, press the button and you’re off to flavor town, very easy to use. Not too heavy, but still feels solid in the hand. The light while you are grinding is nice and bright so I can accurately see how much spice I’m adding to my meals. I love ‘em!

Good quality
Material Type: Updated-Stainless Steel, Material Type: Updated-Stainless Steel
Love this set! The design is very sleek and modern, and the stainless steel looks great on the counter. The charging base is compact, so the grinders stay together and always ready to use. Both the salt and pepper grinders work smoothly and give an even grind with just one button, which is super convenient while cooking. The clear window lets you see how much is left inside, so you know exactly when to refill. Overall, this rechargeable Zadelar set is stylish, easy to use, and a really nice upgrade for everyday cooking and serving at the table.

Easy use, easy grasp salt and pepper grinders
Material Type: Updated-Stainless Steel
Wish I got these earlier as well! Easy to use, easy to fill, easy to charge. Seems quite durable and quality is high, not cheap or pkasticky. Easy to grab unit and press button to dispense. The battery charge life seems long lasting esp since we use these every day for meals. Highly recommend!
