Recombinant Human IL-21 Protein

A DNA sequence encoding the Human IL-21 protein (Q9HBE4) (Gln30-Ser162) was expressed with a polyhistidine tag at the N-terminus.

The Recombinant Human IL-21 Protein is a highly purified and biologically active protein that is produced using recombinant DNA technology. This protein is a member of the interleukin family and is known to play a crucial role in the regulation of immune responses. It is a potent activator of T and B cells and is involved in the differentiation and proliferation of these cells.

The Recombinant Human IL-21 Protein is produced in a mammalian expression system and is purified using a combination of chromatography techniques. The resulting protein is highly pure and has a high specific activity. It is supplied as a lyophilized powder that can be reconstituted in water or buffer solutions.

This protein is suitable for a wide range of applications in research and development. It can be used to study the role of IL-21 in immune responses, as well as in the development of new therapies for immune-related diseases. It can also be used as a standard in immunoassays and as a positive control in cell-based assays.

The Recombinant Human IL-21 Protein is available in various sizes and quantities to meet the needs of different research projects. It is manufactured under strict quality control standards to ensure consistency and reproducibility. The product is shipped at ambient temperature and should be stored at -20°C upon arrival.

In summary, the Recombinant Human IL-21 Protein is a high-quality and biologically active protein that is essential for research in immunology and related fields. Its purity, potency, and consistency make it an ideal tool for a wide range of applications.
