C-X-C motif chemokine 14 protein (Cxcl14) (Active), mouse, recombinant

Organism: Mus musculus (Mouse). Source: E.Coli. Expression Region: 23-99aa. Protein Length: Full Length of Mature Protein. Tag Info: Tag-Free. Target Protein Sequence: SKCKCSRKGP KIRYSDVKKL EMKPKYPHCE EKMVIVTTKS MSRYRGQEHC LHPKLQSTKR FIKWYNAWNE KRRVYEE. Purity: >95% as determined by SDS-PAGE. Endotoxin: Less than 1.0 EU/µg as determined by LAL method. Biological Activity: Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human monocytes is in a concentration range of 1.0-10 ng/ml. Form: Lyophilized powder. 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. Storage: 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. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Chemotactic for CESS B-cells and THP-1 monocytes, but not T-cells. {ECO:0000269, PubMed:10784614}. Reference: n/a. Function: Chemotactic for CESS B-cells and THP-1 monocytes, but not T-cells.
