The Human TMPRSS4 (Transmembrane protease serine 4) QuickTest ELISA Kit measures TMPRSS4 in Human Serum, Plasma, Cell Culture Supernatant, Cell Lysate or Tissue Lysate. This kit was based on sandwich ELISA method. The experiment lasted 120 minutes. Capture antibody was conjugated to an affinity tag that was recognized by a specific antibody coated on the QuickTest plate. Add the Cap/Det Ab working solution into each well, then add the standards and pilot samples into individual wells. If the sample contains TMPRSS4, a capture antibody-TMPRSS4-biotin-detection antibody complex was formed. After incubation, unbound conjugates were removed by wash buffer. HRP-Streptavidin was added. After washing, TMB substrates were added to visualize HRP enzymatic reaction. 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. The concentration of TMPRSS4 in the sample was calculated by drawing a standard curve. The concentration of the target substance is proportional to the OD450 value.

All-Day Comfort for 10+ Hour Workdays. Finally Found a Pair That Holds Up
Size: 12, Color: Black Leather/Black, Size: 12, Color: Black Leather/Black
After years of trying different “comfortable” dress shoes, this is the first pair I’ve owned that I can wear for a full 10+ hour workday without counting down the minutes to take them off. For context, I’m a retail district manager. I’m on my feet most of the day walking stores, standing in conversations, moving constantly. I’ve owned Clarks, Rockport, and even higher-end dress shoes, and while some started out comfortable, none of them held up for an entire day without foot fatigue setting in. These Cole Haan shoes are different. What stands out: All-day comfort: No mid-day foot pain, even after long shifts. Solid construction: Genuine leather that takes and holds a polish well. Supportive sole: Noticeably helps with impact from constant walking. Great value: Performs better than shoes I’ve paid significantly more for. I also appreciate that they hit a nice middle ground stylistically; more business casual than formal, but still sharp enough for most professional environments. For additional context, I am a heavier individual and tend to wear down the outer (lateral) edge of my shoes first. That pattern holds true here as well. The only drawback: After about two months of wearing them 5 days a week (purchased January 7th), the sole shows more wear than I would expect at this point. It’s not a dealbreaker, but it’s the reason I’m giving 4 stars instead of 5. I’ll be including a comparison photo between the worn pair and a new pair for reference. That said, I still expect to get around 8–10 months of use out of them, which at this price point is more than fair. Bottom line: If you need a comfortable, reliable, and reasonably priced work shoe for long days on your feet, these outperform just about everything else I’ve tried, and that’s why I bought a second pair.
