• Host: E Coli
• Purity/Purification: Greater than 99.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
• Form/Format: The XCL1 was lyophilized from a concentrated (1mg/ml) solution in water containing no additives.; Sterile Filtered White lyophilized (freeze-dried) powder.
• Sequence: The sequence of the first five N-terminal amino acids was determined and was found to be Gln-Ser-Glu-Val-Ser
• Sequence Length: 114

• Solubility: It is recommended to reconstitute the lyophilized Lymphotactin in sterile 18M Omega -cm H2O not less than 100 ug/ml, which can then be further diluted to other aqueous solutions.
• Biological Activity: The Biological activity is calculated by its ability to chemoattract human T cells at 10-100ng/ml corresponding to a Specific Activity of 10,000-100,000IU/mg.
• Preparation and Storage: Lyophilized Lymphotactin although stable at room temperature for 3 weeks, should be stored desiccated below -18 degree C. Upon reconstitution XCL1 should be stored at 4 degree C between 2-7 days and for future use below -18 degree C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please avoid freeze-thaw cycles.

Related Product Information for XCL1 active protein

Description: Lymphotactin Human Recombinant produced in E Coli is a single, non-glycosylated, polypeptide chain containing 92 amino acids and having a molecular mass of 10007 Dalton. The Lymphotactin is purified by proprietary chromatographic techniques.

Introduction: Chemokine (C motif) ligand (XCL1) is a small cytokine belonging to the XC chemokine family that is also known as lymphotactin. It is found in high levels in spleen, thymus, intestine and peripheral blood leukocytes, and at lower levels in lung, prostate gland and ovary. Cellular sources for XCL1 include activated thymic and peripheral blood CD8+ T cells. This chemokine attracts T cells. In humans, XCL1 is closely related to another chemokine called XCL2, whose geneis found at the same locus on chromosome 1. XCL1 induces it chemotactic function by binding to a chemokine receptor called XCR1.

NCBI Description

This antimicrobial gene encodes a member of the chemokine superfamily. Chemokines function in inflammatory and immunological responses, inducing leukocyte migration and activation. The encoded protein is a member of the C-chemokine subfamily, retaining only two of four cysteines conserved in other chemokines, and is thought to be specifically chemotactic for T cells. This gene and a closely related family member are located on the long arm of chromosome 1. [provided by RefSeq, Sep 2014]
