The plate has been pre-coated with Porcine SFTPA1 antibody. SFTPA1 present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Porcine SFTPA1 Antibody is added and binds to SFTPA1 in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated SFTPA1 antibody. After incubation unbound Streptavidin-HRP is washed away during a washing step. Substrate solution is then added and color develops in proportion to the amount of Porcine SFTPA1. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm.

The best solar watch under $25 period..
Color: Black, Color: Black
If your looking for a watch under $25, that will NEVER need a new battery this is what you want.. This watch is well built, with its very clear negative display. The band has a quality feel and plenty of length for guys with big wrists.. For under $25 this is one you can't go wrong with, highly recommended!!

Top Notch
Color: Khaki
The size is perfect for my wrist, needed a solar watch for work in rural law enforcement, rechargeable watches weren't cutting it & frustrating when drained, so far this watch works for me, inexpensive so if damage no worries, the design is nice, the display is bright day or night so I can see it. The wrist band is a solid fit. The alarm is loud, if your looking for a work watch to save your quality watches this is for you. I recommend this watch.

Excellent value.
Color: Black
I wanted an inexpensive “work” watch so I could keep my “good” watches from getting beat up. This one is an excellent choice…solar so no battery to replace. Bright light function for night time check. No analog function is the only downside for us old folks. Overall a bargain! 👍

Incredible quality leather—built like a tank!
Color: Carhartt Brown (Trifold), Color: Carhartt Brown (Trifold)
I am incredibly impressed with this Carhartt wallet. Right out of the box, you can tell the full-grain brownish saddle leather is top notch quality. It has a great weight to it, feels incredibly durable, and has that authentic, premium leather smell. The stitching around the edges is heavy-duty and tight, so I don't see this fraying anytime soon.It holds all my cards and cash perfectly without getting uncomfortably bulky in my pocket, and the built-in RFID blocking gives me great peace of mind. It’s starting to break in beautifully and develop a nice patina already. If you want a rugged, functional wallet made from actual good materials that will last for years, this is absolutely worth it. Highly recommend!
