Background

Natural killer protein 30 (NKp30; also known as natural cytotoxicity receptor 3, NCR3; or CD337) is an Ig-like activating receptor of NK cells regulating the cross talk between NK and dendritic cells. It is expressed on the surface of NK cells, recently-expanded γδT cells, activated CD8 cells, and innate lymphocytes. The extracellular part of NKp30 consists of a single N-terminal Ig-like domain, followed by a distinct 15 amino acids long stalk region proximal to the plasma membrane, which is important for receptor signaling. Further, three specific cellular ligands of NKp30 have been identified. NKp30 binds a member of B7 family, in particular B7 homolog 6 (B7-H6). Interaction of NCR3 with B7H6 leads to activation of NK cells and induces cytolysis of target cells resulting in apoptotic cell death. Another NKp30 cellular ligand, BAG-6 is recruited to the cell membrane and interacts with NKp30 in some tumor cells or under the stress conditions. The most recently discovered NKp30 ligand, galectin 3, expressed on the surface of some tumors, almost completely blocks NK cell cytotoxicity.

Mixes drinks well and holds a charge
Color: Silver
I bought this frother to replace a weaker frother I had been using for months. I make iced lattes with instant espresso powder, water, and milk, and this frother does a great job at mixing the powder into the water/milk. It also leaves a nice 1" or so of milk froth on the top. I love that it can be charged with a USB-C cable and doesn't require batteries like many frothers do. It's very powerful for the size.

Powerful!
Color: Lux Galaxy, Size: Rechargeable Z1 Motor Max
This thing is powerful and works great! I was hesitant about some of the negative reviews, but this is worth it so far. I use it every day and haven't charged it in the week that I've had it. Some people complained about turning it off.... It's not that hard. Just hold the button down for a second or two and it shuts off, no fuss. If you tap/press the button you'll cycle through the next speed and then off. I only use the first speed to make my protein shake and matcha. I feel like the high speed would just whip everything to pure foam! I'm hoping this lasts me a long time.

Quiet and Effective frother/mixer and Terrific Customer Service
Zulay Kitchen Powerful Milk Frother Wand We ordered two Zulay frother wands and after just several months of continuous usage one of the units stopped working and the other one was sporadically working, where sometimes it would run “full power” and at other times it was barely spinning or turning the beverage. I called Zulay and gave them my Amazon order number. After the Customer Service rep walked me through some minor things to check on the units she was also convinced that the units were probably defective. She had a replacement sent from Zulay along with a mini as a bonus for our troubles! And she had Amazon ship the other replacement unit. Both shipments arrived promptly within days and we have been using them for months now without any major issues. We use the units (the two “standard” wands) almost every day and they get used two to three times a day. They only take ten to twenty seconds to mix up cocoa powder, hot or cold. And the same goes for different protein powder shakes. What I especially like about these units is that there have been many times when I have had to use them off-hours, like between 5:00 and 6:00 AM. They are Whisper quiet so nobody gets disturbed. One generally can’t do this level of quiet stirring/mixing with a kitchen hand blender/mixer or shake blenders. These Zulay mixing units have really come in “handy” for us. We are very Grateful to Amazon for their prompt delivery, and especially to the Customer Service representative at Zulay for her help, and to Zulay for standing behind their products and providing us with terrific and prompt Customer Service! Thank you! Cheers! November 3, 2025
