Human IL21 Protein, His Tag

Catalog Number: orb1173903

Catalog Number	orb1173903
Category	Proteins
Description	Recombinant Human IL21 with C-terminal 6×His tag
Reactivity	Human
Tag	C-6×His Tag
Form/Appearance	Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8% trehalose is added as protectants before lyophilization. Please see Certificate of Analysis for specific instructions of reconstitution.
Purity	The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining.
Conjugation	Unconjugated
MW	The protein has a predicted molecular mass of 16.3 kDa after removal of the signal peptide.The apparent molecular mass of IL21-His is approximately 15-25 kDa due to glycosylation.
Target	IL21
UniProt ID	Q9HBE4
Source	Mammalian
Storage	Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (Avoid repeated freezing and thawing). Lyophilized proteins are shipped at ambient temperature.
Buffer/Preservatives	Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8% trehalose is added as protectants before lyophilization. Please see Certificate of Analysis for specific instructions.
