Recombinant Human CD14 Protein (Thr20-Cys352), Tag Free
Product Description
Cat
IMP-10204
Official Symbol
CD14
Product Overview
Recombinant human CD14 protein (Thr20-Cys352) without tag was expressed in Chinese Hamster Ovary cell line.
Description
The protein encoded by this gene is a surface antigen that is preferentially expressed on monocytes/macrophages. It cooperates with other proteins to mediate the innate immune response to bacterial lipopolysaccharide, and to viruses. This gene has been identified as a target candidate in the treatment of SARS-CoV-2-infected patients to potentially lessen or inhibit a severe inflammatory response. Alternative splicing results in multiple transcript variants encoding the same protein.

Form
Lyophilized from a 0.2 μm filtered solution in PBS with BSA as a carrier protein.
Molecular Mass
Predicted Molecular Mass: 35.8 kDa
SDS-PAGE: 43-58 kDa, reducing conditions
Protein length
Thr20-Cys352
Bio-activity
Measured by its ability to enhance LPS-stimulated IL-8 secretion by THP-1 human acute monocytic leukemia cells. The ED50 for this effect is 0.75-4.5 ng/mL.
Endotoxin
<1.0 EU/μg of the protein by the LAL method.
Purity
>95%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie Blue Staining.
Storage
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70 centigrade as supplied.
1 month, 2 to 8 centigrade under sterile conditions after reconstitution.
3 months, -20 to -70 centigrade under sterile conditions after reconstitution.
Reconstitution
Reconstitute at 100 μg/mL in sterile PBS containing at least 0.1% human or bovine serum albumin.
