• Applicable Applications for CXCL1 recombinant protein: Cell Assay
• Species: Human
• Endotoxin Level: <1.0EU/ug of recombinant protein as determined by the LAL method
• Sample Cell Assay Data: Determined by the ability to chemoattract human neutrophils using a concentration range of 10.0-50.0ng/mL.
• Reconstitution: A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1mg/ml. This solution can then be diluted into other buffers.

Related Product Information for CXCL1 recombinant protein

Recombinant Human CXCL1 was expressed in E Coli cells. The protein accession number is P09341
A chemokine, the growth regulated oncogene-alpha is identical with MGSA (melanoma growth stimulatory activity) with its new designation being CXCL1. The expression of GRO can be induced by serum or PDGF and/or by a variety of inflammatory mediators, such as IL-1 and TNF, in monocytes, fibroblasts, melanocytes and epithelial cells. In certain tumor cell lines, GRO is expressed constitutively. Similar to other alpha chemokines, the three GRO proteins are potent neutrophil attractants and activators. In addition, these chemokines are also active toward basophils. All three GROs can bind with high affinity to the IL-8 receptor type B.

NCBI Description

This gene encodes a member of the CXC subfamily of chemokines. The encoded protein is a secreted growth factor that signal through the G-protein coupled receptor, CXC receptor 2. This protein plays a role in inflammation and as a chemoattractant for neutrophils. Aberrant expression this protein is associated with the growth and progression of certain tumors. A naturally occurring processed form of this protein has increased chemotactic activity. Alternate splicing results in coding and non-coding variants of this gene. A pseudogene of this gene is found on chromosome 4. [provided by RefSeq, Jan 2012]

Uniprot Description

CXCL1: Has chemotactic activity for neutrophils. May play a role in inflammation and exerts its effects on endothelial cells in an autocrine fashion. In vitro, the processed forms GRO- alpha(4-73), GRO-alpha(5-73) and GRO-alpha(6-73) show a 30-fold higher chemotactic activity. Belongs to the intercrine alpha (chemokine CxC) family.
