Product Features

High biocompatibility: The surface modification of polystyrene microspheres gives them good compatibility in biological systems.

High sensitivity: Due to the high affinity between streptavidin and biotin, these particles exhibit high sensitivity in detection applications.

High specificity: The streptavidin biotin system provides highly specific binding.

Application Fields

 

Biological detection and diagnosis: Utilizing the high affinity between streptavidin and biotin, polystyrene microspheres can serve as a detection platform for capturing and detecting specific biomolecules, such as proteins, nucleic acids, etc.

Immunoassay: In the development of lateral flow chromatography reagents, polystyrene microspheres modified with streptavidin can be used for immunoassay, providing highly specific and sensitive detection results.

Biosensors: Microspheres can be used as a part of biosensors, utilizing their surface modified properties to detect and analyze specific biomolecules.

Quantitative detection of biomolecules: Streptomycin modified polystyrene microspheres can be used to develop quantitative detection reagents, especially in the detection of biomolecules that require high affinity and specificity.

Nice Product and Customer Service
I ordered this BlastIR Wireless Pro IR Repeater from Sewell to replace a wired version of an IR repeater from another company. We have moved our TV on to a wall location and are in the process of hiding all the wiring out of sight behind walls and/or in a cabinet. We still have some wires to go, but this product has enabled us to eliminate the IR wiring all together. It's a real improvement in both looks and performance over the cheaper, wired version we originally tried. The BlasterIR's Receiver is the component that faces the room and receives the IR signal from our remote controls. It's small enough to fit in the space between our sound bar and the bottom of the TV. It's range is great for our room size (about 22' long and 18' wide) and picks up the remotes signal from a side angle that's almost parallel to the TV itself. The receiver is powered through one of the USB ports integrated into the TV (although the device itself supports either a USB or regular plug-in option). I haven't used them yet but Sewell appears to have provided a few options to help with affixing the IR devices in their final positions including some adhesive pads and a magnetic pad option as well. I'm still playing around with the permanent placement of the IR Blaster Emitter. It sits inside a closed cabinet and faces the concealed cable box receiver, router and DVR components. It retransmits the various IR signals it receives from the IR receiver by blasting that signal to anything it faces. I just placed it in the cabinet about 5" away from the devices I wanted to control, plugged it in and it worked with no other set up. So far the BlastIR is working seamlessly and with much better function response time than the cheaper IR version we'd tried at first. The lag time between when a button is pressed on the remote control and the action taking place on the device I'm communicating with is minimal. The emitter itself is plugged into an outlet on a surge protector powering the other in-cabinet devices, although it too could be powered via the provided USB connection if desired. As a note, we did experience a shipping issue during our ordering process. The order it self was processed quickly and shipped in a timely manner. However, there was an issue with our actual receipt of the product and the USPS who reported it delivered to our mailbox when in fact it had not been. Regardless, we reached out to Sewell directly and they quickly resolved the issue for us with no problems and in a timely manner. I would recommend both this IR Blaster Pro product as well as Sewell as a trusted company itself.

Does NOT Transmit Through Walls
Quick and easy setup! Works great within the room. However, will not work effectively between walls (i.e. - AV closet to living room).

Works perfectly - great product
My MBR TV set-up incorporates a cable box set up in a closet about 50 feet from the TV (hung over a fireplace). When it was set up the A/V used a wired infra-red set up that was wired thru the walls, under the floor, into the closet. Unfortunately some mice nibbled on the wiring and it does not work. I have tried everything including the Next Generation extender (over the years bought 6 of them for different TV's) and most recently the Startech. The Next Generation have not been updated in years and over time completely lose their ability to operate. No customer service at all; emails go into a black hole. I had high hopes for the Startech. Easy to set up and worked out of the box. The problem is the lag time. I could live with it when watching live TV, but it was totally impossible when it came to playing back programs from the DVR (which is cloud based). I was losing hope until I tried the Sewell Blaster. Took me less then 5 minutes to set up and it worked instantly. Little or no lag to speak of and I couldn't be happier. NB. Speaking of Sewell, the absolutely BEST way to control your HDMI based TV is the Sewell Direct SW-30062 Dual Band InjectIR sold by Amazon for $55. This is truly plug 'n play and operates with absolutely no lag. Bought 2 of these to operate TV's in my apartment where I had to hide boxes in closets. Well made, great instructions (coordinated with the devices) and I just love this product. I bought mine direct from Sewell ) same price) because I couldn't find them on Amazon when I needed them, but they have a great return policy and I'm told great C/S. If you can't use these then go for the Blaster.

Excellent fit and value - recommended buy
Size: 3+12+12+2+1 pack
I rarely write reviews, but I'm so impressed by the fit and quality of this set that I made an exception. I'd been running my eufy 11S without brushes, and have been cleaning and reusing the filters for a while now and finally decided to buy replacements. The kit came packed well with everything in order and no damage. I replaced all of the worn parts and installed the brushes and did a test run - everything worked great. I expected some fitment issues because I've seen that with other kits, but I had no issues. The fact that you get multiples of almost everything is icing on the cake. Oh, and I wasn't paid or given anything in exchange for this review, as much as that's worth now, haha. I can recommend getting this kit for your robot vacuum, if it's the right set for your model.
