Goat Anti-Human Eotaxin-2
Antigen Affinity Purified
(CCL24, MPIF-2, CkB-6, SCYA24)
Polyclonal Antibody
Prod. No.: E117
Host: Goat
Pkg. Size: 1.0 mg, 100 µg
Storage: -20°C to -70°C
Description
Specificity:
Goat Anti-Human Eotaxin-2 recognizes Human Eotaxin-2. 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-2 is a CC chemokine that is a specific agonist for the chemokine receptor CCR3. It is produced by activated monocytes and T lymphocytes. Eotaxin-2 induces chemotaxis of eosinophils as well as basophils and the release of histamine and leukotriene C4 from basophils. Eotaxin-2 has the same efficacy as eotaxin, but is somewhat less potent.1 Additionally, Eotaxin-2 inhibits the proliferation of multipotential hematopoietic progenitor cells.
Known Species Cross Reactivity: Hu+
Immunogen
Purified Recombinant Human Eotaxin-2 (>98%)
Formulation
This 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 5.0% w/v trehalose with no calcium, magnesium, or preservatives present.
Reconstitution
We suggest aseptically reconstituting this lyophilized, antigen affinity purified polyclonal antibody with 1 µl of sterile 1X PBS pH 7.2-7.3. This will result in a final antibody concentration of 0.1 mg/ml.
Endotoxin
<0.1 EU/µg as determined by the LAL method
Storage and Stability
The lyophilized antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for twelve months from date of receipt. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, 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
Indirect ELISA, IHC (NBF/Par.), N, WB
Indirect ELISA: This antibody can be used in an indirect detection ELISA at 0.5 - 1 µg/ml with a suitable second step reagent such as Donkey Anti-Goat IgG (H&L)-Horseradish Peroxidase (Leinco Prod. No.: G505). The detection sensitivity of this indirect ELISA for Human Eotaxin-2 is approximately 0.06 ng/well.
IHC (NBF/Par.): This antibody should give satisfactory staining results when used at a concentration of 15 µg/ml. The recommended secondary antibody for IHC is Donkey Anti-Goat IgG (H&L)-Horseradish Peroxidase (Leinco Prod. No.: G505). For chromogenic detection with high signal and low background use 3, 3'-Diaminobenzidine Tetrahydrochloride (DAB) Substrate Kit (Leinco Prod. No.: D100) or Optional Metal Enhanced DAB Substrate Kit (Leinco Prod. No.: K107).
Neutralization: This antibody is useful for neutralization of Human Eotaxin-2 bioactivity. The antibody dose required to neutralize 50% (ND50) of the biological activity of Human Eotaxin-2 (at 0.1 ng/ml) is 0.5 - 2.5 µg/ml.
Western Blotting: To detect Human Eotaxin-2 this polyclonal antibody can be used at a concentration of 0.1 - 0.2 µg/ml. This polyclonal antibody should be used in conjunction with compatible second-step reagents such as Donkey Anti-Goat IgG (H&L)-Horseradish Peroxidase (Leinco Prod. No.: G505) 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 Eotaxin-2 is 2 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.
