Background

Spike (S) glycoprotein is the largest of the four major structural proteins found in coronaviruses.The spike protein assembles into trimers that form large structures, called spikes or peplomers,that project from the surface of the virion.The function of the spike glycoprotein is to mediate viral entry into the host cell by first interacting with molecules on the exterior cell surface and then fusing the viral and cellular membranes. Spike glycoprotein is a class I fusion protein that contains two regions, known as S1 and S2, responsible for these two functions.

Obsessed With This Ultra Soft, Fluffy, Cozy Blanket
Color: 02 Crystal Pink, Size: Twin (60" x 80"), Color: 02 Crystal Pink, Size: Twin (60" x 80")
I absolutely love this blanket. I ordered the crystal pink color in the 60x80 size to use as a throw blanket for my new cloud couch in my office, and honestly it ended up being exactly what I was hoping for. The material is incredibly soft, fluffy, and comfortable without feeling thin or cheaply made. I’ve actually been searching for another blanket similar to one I previously owned that eventually got a hole in it, and this one gave me that same cozy feeling immediately. It’s one of those blankets you instantly want to curl up in the second you touch it. One thing I really liked is that the bubble texture actually has dimension and volume to it. A lot of blankets advertised with this kind of design end up looking flat in person, but this one genuinely has that plush “bubble” effect and makes the blanket feel extra cozy and luxurious. The size is also great. It’s large enough to comfortably use on a couch while still being big enough for a twin bed if you wanted to use it that way. For me personally, it’s the perfect oversized throw blanket size. I honestly have nothing negative to say about it. The quality feels great, the stitching looks well done, the color is beautiful, and overall it feels thoughtfully made rather than cheaply mass produced. For around $25, I absolutely think it’s worth it. This has easily become one of my favorite cozy blankets in the house.

Mediocre and lacks required fabric content label
Color: 01 Off White, Size: Twin (60" x 80"), Color: 01 Off White, Size: Twin (60" x 80")
I am a "blanket person," meaning I love to be cozy, curled up on the couch, watching movies with my family, and using many different layers and types of blankets on my bed for different seasons. I was excited to order this 3D bubble fleece blanket by Lotus Karen because I have another 3D bubble fleece throw blanket that I absolutely love. The other one has a sherpa lining, which makes it a bit too warm for warmer seasons. This one by Lotus Karen is unlined, which I expected as the listing doesn't say it is lined. However, I'm feeling let down over the softness of the fleece compared to my other one. They all look similar in list photos, but they do not feel the same. After I unfurled this one onto my bed to let it fluff up, which it did after 90-minutes, but instead of the pile feeling plush and silky (like faux rabbit) this one feels more rough. It's not as high quality fleece, even though it looks the same in photos. Undeterred, I still really wanted to like this blanket and went to put it into the laundry, hoping it would bring out the best in it. However, I noticed that there is no fabric content label at all. Not just missing care instructions, but no label of any kind. Under the Federal Trade Commission (FTC) Textile Products Identification Act, it is a violation of United States federal law to sell a textile product that fails to plainly disclose its constituent fiber percentages, country of origin, and registered manufacturer identity physically attached to the product. Having the information on the online listing does not meet this requirement. Because the material is somewhat mediocre, I would have given it three stars. But because it fails to meet basic consumer protection laws, it loses all.

VERY SOFT; MY DOG’S ALREADY APPROPRIATED IT
Color: 01 Off White, Size: Twin (60" x 80")
You know a blanket’s soft when my dog immediately tries to appropriate it. This is incredibly soft, and actually pretty light; it makes for a good spring or summer blanket, or a throw in addition to something else in colder weather. (The twin is big enough that you can double it up over yourself to make it thicker in colder months.) I’m not sure while it’s called a “bubble” blanket - there is a very gentle egg crate shape to it, but it’s not rigid at all, and not dual-layer or filled with air or anything. It’s a very comfy throw (my dog can also attest to that) and for ~$20 (at the time of this review), it’s a great deal. I haven’t noticed any shedding, either, but I’m going to wash it on as gentle a cycle I can, to be safe.

This Blanket Feels Like a Warm Hug 🖤”
Size: Throw50" x 60", Color: Black, Size: Throw50" x 60", Color: Black
This faux fur throw blanket is incredibly soft and cozy, making it perfect for relaxing on the couch or adding extra warmth to a bed. The fluffy texture feels plush and comfortable, while the dark color gives it a modern and elegant look. I like how it instantly makes the space feel more inviting and stylish. It’s lightweight enough for everyday use but still feels warm and comfortable during cooler evenings. The material also looks beautiful draped over furniture as part of the décor. Overall, it’s a great decorative and functional blanket for anyone looking to add comfort and a cozy touch to their living space.”

Absolutely Luxurious, Mushu-Approved, and Easy to Care For!
Size: Throw50" x 60", Color: Pink, Size: Throw50" x 60", Color: Pink
​I am absolutely thrilled with this faux fur blanket! From the moment I pulled it out of the packaging, the quality was immediately apparent. The fur is incredibly plush, thick, and unbelievably soft, it truly feels like wrapping up in a cloud. It's the perfect weight, too: cozy on a chilly evening, but not stifling. ​What really sets this blanket apart is the quality and durability. I can confirm that this blanket does not pill, which is a huge bonus. Even better, it holds up perfectly in the wash. I've washed it several times now, and there has been zero shedding, either in the washer/dryer or after it comes out. It remains just as soft, fluffy, and luxurious as the day I bought it, making maintenance incredibly easy. ​But the real testament to this blanket's quality comes from my dog, Mushu! I bought it for myself, but it has quickly become his favorite spot in the house. If he's not actively on a walk or eating, you can guarantee he's curled up on "the fuzzy blanket," completely buried in the softness. ​If you're looking for a blanket that is the definition of comfort, luxury, and warmth, and is also durable and holds up perfectly to washing, look no further. This is a must buy!
