Description

Specificity:

Goat Anti-Human Eotaxin-3 (CCL26) recognizes Human CCL26. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.

Background:

Eotaxin-3/CCL-26 belongs to a family of CC chemokines, which are potent chemoattractants for eosinophils that signal through the CCR3 receptor. ¹ It is produced by endothelial cells stimulated with IL-4 or IL-13. Eotaxin-3 selectively targets cells expressing CCR3, including eosinophils, basophils, T cells and monocytes. It has been reported that eotaxin-3 is an antagonist for CCR2.² Eotaxin-3 has similar activity to Eotaxin and Eotaxin-2, but the three Eotaxins share only a low degree of sequence homology. Eotaxin-3 is up-regulated in the context of a T helper 2 mediated inflammatory bowel disease via the signal transducer and activator of transcription 6, thus suggesting that the intestinal epithelium actively participates in the recruitment of eosinophils at the site of inflammation.¹

Immunogen

E. coli-Derived Recombinant Human Eotaxin-3 (aa 24 - 94)

Formulation

This biotinylated antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 containing 50 µg of bovine serum albumin per µg of antibody with no calcium, magnesium, or preservatives present.

Reconstitution

We suggest aseptically reconstituting this biotinylated, lyophilized, antigen affinity purified polyclonal antibody with 1 ml of sterile 20 mM Trizma base, 0.15 M sodium chloride (1X Tris Buffered Saline) pH 7.2-7.3, containing 0.1% w/v bovine serum albumin (BSA). This will result in a final biotinylated antibody concentration of 50 µg/ml.

Storage and Stability

The lyophilized, biotinylated antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for up to twelve months from date of receipt. The reconstituted bioin conjugate can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted conjugate, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.

Reported Applications

ELISA Det, WB

Western Blotting: To detect Human CCL26 this biotin conjugate can be used at a concentration of 0.1 - 0.2 µg/ml. This biotin conjugate should be used in conjunction with compatible second-step reagents such as UltraAvidin™- Horseradish Peroxidase (HRPO) (Leinco Prod. No.: A106) and a chromogenic substrate such as TMB HRPO Membrane/IHC Substrate UltraSensitive™ One Component "Ready Use" (Leinco Prod. No.: T343). The detection limit for Human CCL26 is 1 ng/lane under either reducing or non-reducing conditions. The sensitivity of detection may increase up to 50 fold when a chemiluminescent substrate is used.

Each investigator should determine their own optimal working dilution for specific applications.
