Recombinant Human CCL21 Protein, His-tagged

• Cat.No.: CCL21-2148H
• Product Overview: Recombinant Human CCL21 Protein (Ser24-Pro134) with a N-His tag was expressed in E. coli.

Specification

• Description: This antimicrobial gene is one of several CC cytokine genes clustered on the p-arm of chromosome 9. Cytokines are a family of secreted proteins involved in immunoregulatory and inflammatory processes. The CC cytokines are proteins characterized by two adjacent cysteines. Similar to other chemokines the protein encoded by this gene inhibits hemopoiesis and stimulates chemotaxis. This protein is chemotactic in vitro for thymocytes and activated T cells, but not for B cells, macrophages, or neutrophils. The cytokine encoded by this gene may also play a role in mediating homing of lymphocytes to secondary lymphoid organs. It is a high affinity functional ligand for chemokine receptor 7 that is expressed on T and B lymphocytes and a known receptor for another member of the cytokine family (small inducible cytokine A19).
• Source: E. coli
• Species: Human
• Tag: N-His
• Form: Freeze-dried powder
• Molecular Mass: Predicted Molecular Mass: 13.5 kDa
  Accurate Molecular Mass: 18 kDa
• Protein length: Ser24-Pro134
• Endotoxin: <1.0 EU per 1µg (determined by the LAL method).
• Purity: > 97%
• Applications: Cell culture; Activity Assays.
• Stability: The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37 centigrade for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.
• Storage: Avoid repeated freeze/thaw cycles. Store at 2-8 centigrade for one month. Aliquot and store at -80 centigrade for 12 months.
• Storage Buffer: 20mM Tris, 150mM NaCl, pH8.0, containing 1mM EDTA, 1mM DTT, 0.01% SKL, 5% Trehalose and Proclin300.
• Reconstitution: Reconstitute in 20mM Tris, 150mM NaCl (PH8.0) to a concentration of 0.1-1.0 mg/mL. Do not vortex.
