XCL2 Protein, Human, Recombinant (His Tag)

XCL2 is a small cytokine belonging to the XC chemokine family. Chemokines are a group of cytokines. Members of this group of so-called C-Chemokines belong to the SCY family of cytokines and are designated XCL (L for ligand) followed by a number. XCL2 is the new designation of SCM-1-beta. XCL2 is highly related to another chemokine called XCL1. XCL2 gene is located on chromosome 1 in humans. XCL2 is predominantly expressed in activated T cells, but can also be found at low levels in unstimulated cells. XCL2 induces chemotaxis of cells expressing the chemokine receptor XCR1. XCL2 gene has been proposed to participate in pathways (Chemokine signaling pathway, Cytokine-cytokine receptor interaction) and processes (blood circulation, signal transduction, chemotaxis, immune response) . XCL2 are expected to have molecular function (chemokine activity) and to localize in various compartments (extracellular space, extracellular region) . A putative protein interactor has been described (XCR1) . The spliced mRNA putatively encodes a good protein, containing small cytokines (intecrine / chemokine), interleukin-8 like domain; the complete protein appears to be secreted.

At Leading Biology, the biological activity of a recombinant protein is routinely measured using a bioassay, e.g. chemotaxis or cell proliferation assay, enzyme assay, or a functional ELISA. When a recombinant protein is an enzyme, specific activity is derived from an enzymatic assay. Each enzyme is tested for potency by cleavage of a substrate. We are in the process of updating the biological activity data. If you have any questions regarding this update, please feel free to contact our technical support team.

Lyophilized from sterile 20mM Tris, 500mM NaCl, pH 7.4, 10% gly Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

The secreted recombinant human XCL2 comprises 103 amino acids and has a predicted molecular mass of 11.7 kDa. The apparent molecular mass of rh XCL2 is approximately 18-20 kDa in SDS-PAGE under reducing conditions.

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
