The Recombinant Human CD44 Protein is a biologically active recombinant protein that plays a significant role in various cellular processes and signaling pathways in human biology. This protein is widely employed in immunological research, cell biology studies, protein-protein interaction analyses, and therapeutic development, providing researchers with a reliable tool for investigating CD44 function and its implications in health and disease.
This product (SKU: RPCB0636) is produced using HEK293 cells and features a C-hFc tag for convenient detection and purification. The protein exhibits a calculated molecular weight of 53.57 kDa with an observed molecular weight of 70-100 kDa under denaturing conditions, achieving ≥ 95 % as determined by SDS-PAGE;≥ 95 % as determined by HPLC., ensuring exceptional quality and consistency for research applications.
High quality, high purity and low endotoxin recombinant Recombinant Human CD44 Protein (RPCB0636), tested reactivity in HEK293 cells and has been validated in SDS-PAGE.100% guaranteed.
Endotoxin:
< 1 EU/μg of the protein by LAL method.
Purity:
≥ 95 % as determined by SDS-PAGE;≥ 95 % as determined by HPLC.
Formulation:
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution:
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
Storage:
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
CD44 is a hyaluronan binding cell surface signal transducing receptor that influences motility, cell survival and proliferation as well as the formation of tumor microenvironment. CD44 contains two variable regions encoded by variable exons. Alternative splicing, which is often deregulated in cancer, can produce various isoforms of CD44 with properties that may have different tissue specific effects and therefore even diverse effects on cancer progression
Recombinant Human CD44 Protein was determined by Tris-Bis PAGE under reducing conditions.
The purity of Human CD44 is greater than 95% as determined by SEC-HPLC.
