Tag	His Tag (N-term)
Predicted MW	The protein has a calculated MW of 18.08 kDa. The protein migrates as 18 kDa under reducing condition (SDS-PAGE analysis).
Purity	>98% as determined by SDS-PAGE.
Buffer	The protein was lyophilized from a 0.2 µm filtered solution containing containing 0.05% sarkosyl, in 1X PBS, pH 8.0.
Applications	Cell culture
Storage	Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.
Bioactivity	Measure by its ability to induce IL-8 secretion in human PBMCs. The ED₅₀ for this effect is <0.6 ng/mL.
Endotoxin	<0.1 EU per 1 μg of the protein by the LAL method.

Synonyms	soluble CD27 Ligand, sCD27 Ligand, TNFSF7, CD70
Summary	Human CD27L is also named for CD70 which is one member of TNF family. Human CD27L is expressed on T and B lymphocytes and mature DCs. It binds the CD27, which is on the antigen-presenting cells. Human CD27L is a 23 kDa cytokine with 154 amino acid residues which is a transmembrane glycoprotein. Human CD27L plays an important role in the regulation of T cell proliferation which is also a good target of cancer immunotherapy.
