Optimized DNA sequence  encoding extracellular domain of Human CD69 (SER62 - LYS199) including a C-terminal His tag was expressed in HEK293 cells.

Molecular weight:

Recombinant Human CD69 is a protein consisting of 137 amino acid residue subunits,due to glycosylation migrates as an approximately as 23kDa band protein on reduced SDS-PAGE.

>95%, as determined by SDS-PAGE and HPLC

Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).

Recombinant human CD69 is lyophilized  from 0.2 μm filtered PBS solution,  pH7.2 ,  5% Trehalose.

A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.

Recombinant CD69 can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to -70°C for twelve months.

Avoid repeated freeze/thaw cycles.

CD69 is a type II C-type lectin involved in lymphocyte migration and cytokine secretion. CD69 is a disulfidelinked homodimer and a member of the natural killer receptor family. Its genes are located in a conserved genomic region known as the natural killer gene cluster on mouse chromosome 6 and human chromosome 12.CD69 expression represents one of the earliest available indicators of leukocyte activation and its rapid induction occurs through transcriptional activation. In contrast to other members of the NK C-type lectin cluster, CD69 has not been established to have a role in NK cell recognition of target cells. In transgenic overexpression studies, CD69 inhibited T cell egress from the thymus
