Tag Info
Tag-Free
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Form
Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer
Lyophilized from a 0.2 µm filtered PBS, pH 7.4
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Lead Time
5-10 business days
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

Description
Lymphotactin (XCL1) is the sole C-class chemokine, uniquely possessing a single disulfide bond and signaling exclusively through XCR1 to recruit specific immune cell subsets. This tag-free recombinant rat XCL1, encompassing the full mature sequence (aa 22–114), demonstrates potent chemotactic activity with an ED50 below 100 ng/ml in XCR1-transfected BaF3 migration assays, corresponding to a specific activity exceeding 1.0 × 10⁴ IU/mg. These functional data support use in chemotaxis and transwell migration assays, XCR1 signaling pathway dissection, in vivo rat models of dendritic cell trafficking and inflammation, and as a reference standard in cytokine detection platforms. Purity exceeding 97% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the stringent criteria required to prevent LPS-driven artifacts in sensitive immune cell functional assays.
