Description

Protein A - 20nm gold conjugate is a valuable tool for researchers in the fields of immunology and cell biology. The conjugate consist of Protein A, a bacterial cell wall protein that has high affinity for the Fc portion of immunoglobulins (specifically IgG), linked to colloidal gold particles. Protein A - 20nm gold conjugate allows for the convenient and rapid conjugation of Fc-containing antibodies to gold surfaces, providing a versatile and reliable method for the detection and visualization of specific proteins, antigens or molecules in biological samples. Compared with traditional immunohistochemistry techniques, it has higher sensitivity and specificity and can recognize multiple antigens simultaneously.

Applications

• Immunohistochemistry. Protein A - 20nm gold conjugate is commonly used in immunohistochemistry studies to detect and localize specific proteins, antigens or molecules in tissues and cells. The gold nanoparticles provide a visible signal that can be easily detected under a microscope.
• Protein purification. Protein A - 20nm gold conjugate can be used for the purification of antibodies or other proteins. Protein A can bind to the Fc region of antibodies with high specificity, thus facilitating the isolation and purification of specific proteins.
• Diagnostic assays. Protein A - 20nm gold conjugate can also be used in diagnostic assays for specific antibodies or antigens.

Storage

• Store undiluted in storage buffer at 2-8 °C. Stable for 4 months if stored as specified.
• It is important to note that storing conjugate at working dilution may result in performance loss.
