Specifications

Product Data
Species	Human
Expression Host	E. coli
Expression cDNA Clone or AA Sequence	Protein Sequence (showhide) ASVATELRCQCLQTLQGIHPKNIQSVNVKSPGPHCAQTEVIATLKNGRKACLNPASPIVKKIIEKMLNSDKSN with polyhistidine tag at the N-terminus.
Tag	His Tag (N-term)
Predicted MW	The protein has a calculated MW of 8.67 kDa. The protein migrates as 10 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 1X PBS, pH 7.4.
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 chemoattract BaF3 cells transfected with human CXCR2. The ED₅₀ for this effect is <3 ng/mL.
Endotoxin	<0.1 EU per 1 μg of the protein by the LAL method.
Reference Data
UniProt ID	P09341
Synonyms	GRO-α: MGSAα, NAP-3, GRO1
Summary	C-X-C motif chemokine 1 (CXCL1) also named Growth-regulated oncogene alpha (GROα), which is a chemokine of the intercrine alpha family. CXCL1 is a 7.9 kDa protein containing 73 amino acid residues. CXCL1 is expressed in immune cells such as macrophage and neutrophils. CXCL1 plays an important role with immune responses and cancer progression. CXCL1 activates the cell signal transduction with casepas1 that affect the cell proliferation, differentiation and migration.
