The Donkey Anti-Goat IgG/Gold 20nm is a versatile antibody conjugate suitable for various applications including Immunogold Silver Staining (IGS), Immunogold Chromogenic Amplification (GICA), and Immunoelectron Microscopy (IEM).

Immunogold Silver Staining (IGS) Protocol:

Reagents or buffers: Donkey Anti-Goat IgG/Gold 20nm, silver enhancement solution, and PBS.

Sample preparation: Prepare tissue sections or cell samples on glass slides.

Antibody incubation: Incubate samples with primary goat antibody followed by Donkey Anti-Goat IgG/Gold 20nm at a dilution of 1:20-200.

Washing or detection: Wash samples with PBS and detect using silver enhancement solution.

Technical notes: Optimize silver enhancement time to avoid over-staining.

Immunogold Chromogenic Amplification (GICA) Protocol:

Reagents or buffers: Donkey Anti-Goat IgG/Gold 20nm, chromogenic substrate, and PBS.

Sample preparation: Prepare tissue sections or cell samples on glass slides.

Antibody incubation: Incubate samples with primary goat antibody followed by Donkey Anti-Goat IgG/Gold 20nm at a dilution of 1:20-200.

Washing or detection: Wash samples with PBS and detect using chromogenic substrate.

Technical notes: Choose the appropriate chromogenic substrate for the desired colorimetric reaction.

Immunoelectron Microscopy (IEM) Protocol:

Reagents or buffers: Donkey Anti-Goat IgG/Gold 20nm and PBS.

Sample preparation: Prepare ultrathin tissue sections on grids.

Antibody incubation: Incubate samples with primary goat antibody followed by Donkey Anti-Goat IgG/Gold 20nm at a dilution of 1:20-200.

Washing or detection: Wash samples with PBS and view using a transmission electron microscope.

Technical notes: Optimize sample preparation and antibody incubation conditions for optimal labeling.

IGS=1:20-200;

GICA=1:20-200.

**GICA Protocol**

Use assay conditions validated for GICA, apply Donkey Anti-Goat IgG/Gold 20nm at the recommended working dilution, include proper positive and negative controls, perform thorough wash steps, and document incubation time, temperature, and detection conditions for reproducible performance. Recommended dilution: IEM=1:20-200;

IGS=1:20-200;

GICA=1:20-200.

**IEM Protocol**

Use assay conditions validated for IEM, apply Donkey Anti-Goat IgG/Gold 20nm at the recommended working dilution, include proper positive and negative controls, perform thorough wash steps, and document incubation time, temperature, and detection conditions for reproducible performance. Recommended dilution: IEM=1:20-200;

IGS=1:20-200;

GICA=1:20-200.

Precautions

Store at 2-8°C, handle with care, use appropriate controls, and optimize antibody dilution and incubation conditions for each application.
