Description

Specificity:

Goat Anti-Human Desmoglein-2 (DSG2) recognizes Human DSG2. 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:

Desmoglein 2, also known as DSG2, is a human gene. Desmosomes are cell-cell junctions between epithelial, myocardial, and certain other cell types. Desmoglein 2 is a calcium-binding transmembrane glycoprotein component of desmosomes in vertebrate epithelial cells. It provides cellular adhesion and forces transduction by cell-to-cell anchorage. ¹ It also plays a role in embryonic stem cell proliferation.

Known Species Cross Reactivity: Hu+

Immunogen

NS0-Derived Recombinant Human Desmoglein-2 Extracellular Domain

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, WB

Indirect ELISA: This antibody can be used in an indirect detection ELISA at 0.5-1.0 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 Desmoglein-2 is approximately 0.2 ng/well.

Western Blotting: To detect Human Desmoglein-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 Desmoglein-2 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.
