Description
RUO Recombinant Human IL-21 Protein is a research-use-only recombinant cytokine intended for controlled laboratory use in cell culture and stem cell research. This high-purity human interleukin-21 preparation is animal- and carrier-protein-free and exhibits low endotoxin levels, supporting clean experimental conditions and defined culture systems. Offered as 1 pc with a net weight of 0,002 kg, it provides a compact format for specialised RUO workflows. Popular applications include cell culture assays, pluripotency maintenance and stem cell differentiation, where reliable cytokine input is essential. Laboratories can incorporate the protein into media formulations and functional assays without introducing undefined animal-derived carriers. The material from manufacturer Sartorius aligns with protocols that prioritise high purity and low endotoxin burden for reproducible results. Researchers apply it when maintaining pluripotent states, supporting differentiation steps or running cell culture assays under tightly controlled conditions. Its focused specification profile makes it suitable for method development and routine cytokine supplementation in advanced cell biology laboratories.
This article is part of Recombinant proteins & cytokines, in Antibodies & ELISA kits.

Questions about Recombinant Human Interleukin-21
What is this article?
Recombinant Human Interleukin-21 is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Recombinant proteins & cytokines, inside Antibodies & ELISA kits, in Microbiology lab supplies.
A recombinant protein or cytokine is a stated sequence expressed in a stated host, sold by mass or by activity. Tags, such as His or Fc, change the molecule. Endotoxin level matters for anything that will meet a cell. Activity units and micrograms are not the same purchase.
An antibody binds one target. A primary antibody binds the molecule of interest. A secondary antibody binds the primary and usually carries the signal, an enzyme or a dye. An ELISA kit is that binding arranged in a well so the amount of target becomes a colour. The host species, the clone, the antigen and the stated application are the specification. A name alone is not. The literature is on PubMed. Sequences of the targets are on NCBI Nucleotide. Reference material is catalogued by ATCC.
