Product Specification
| Theory | This method uses one-step enzyme-linked immunosorbent ELISA. Samples containing CHOK1 HCP can be simultaneously reacted with HRP-labeled goat anti-CHOK1 antibodies and anti-CHOK1 antibodies coated on enzyme plates to finally form a sandwich complex of solid phase antibodies-HCP-labeled antibodies. Unbound antigen antibodies can be removed by washing the plate. After the TMB substrate is added to the well to complete the reaction, the color development is stopped after the stop solution is added, and the OD or absorbance value of the reaction solution at 450/650 nm is read with a microplate reader. The OD value or absorbance value is proportional to the HCP content in the solution. From this, the HCP concentration in the solution can be calculated from the standard curve. | |||||||||||||||||||||||||||||||||||||||||||||
| Description | Host Cell Protein (HCP) secreted by CHO (Chinese Hamster Ovary) host cells is likely to cause contamination of biological products. Failure to adequately remove contaminants in the early stage of drug development may lead to a decrease in drug efficacy or induce an immune response. The kit can quantitatively detect the residue of host cell protein in bioengineering pharmaceuticals with high sensitivity, optimize the process flow and ensure the safety of biological products. Product parameters: 1. Sensitivity: 1ng/mL 2. Detection range: 3-100ng/mL 3. Precision: intra-batch coefficient of variation ≤ 10%, inter-batch coefficient of variation ≤ 15% 4. HCP coverage: more than 80% 5. Specificity: This kit is universal because it can specifically react with CHOK1 HCP without relying on the purification process |

Color: Gray, Size: Standard (20" X 26")
I absolutely love these LUXEAR pillowcase They feel cool and soft and they really help keep my pillow fresh and comfortable throughout the night.

Not worth it
Color: Gray, Size: King (20" X 36")
These start out nice and cool but within minutes your body heat turns them warm. Not worth the money.

Great cooling effect!
Color: Stretch Blue, Size: Queen (20" X 30")
I love these pillow cases! They are the best cooling pillowcases I have found. They do still eventually absorb the body heat and need to be flipped over but so far, the cooling effect of these cases outlasts the rest. I have had them for 5 years now and will not use any other cases. They are smooth like silk so I think they are good for my hair as well. The color is pretty close to what is shown in the picture and they fit most standard pillows.

Excellent pillow case
Color: Gray, Size: Standard (20" X 26"), Color: Gray, Size: Standard (20" X 26")
I bought this Luxear from pillowcase a few days ago and I’m very happy with it.
The standard size fits my pillows perfectly, and the gray color looks modern and goes well with my bedding .
I love it because It has two sides: one with cooling fabric that really feels fresh to the touch (perfect for hot nights), and the other side made of soft cotton, which feels cozy and comfortable.
After just a few days of use, I already notice the difference.
I sleep much more comfortably and no longer wake up feeling too warm.
The material feels high quality and durable. It doesn't have any strange smell which I love from the first moment
Definitely a great purchase!
