General description

Human IgGs are glycoprotein antibodies that contain two equivalent light chains and a pair of identical heavy chains, with molecular weight of 50kDa and 25kDa respectively. IgGs have four distinct isoforms, ranging from IgG1 to IgG4. These antibodies regulate immunological responses to allergy and pathogenic infections. IgGs have also been implicated in complement fixation and autoimmune disorders. Goat anti-human IgG binds to human IgG. Immunoglobulin G (IgG) is part of the immunoglobulin family and is a widely expressed serum antibody. The primary structure of this antibody also contains disulfide bonds involved in linking the two heavy chains, linking the heavy and light chains and resides inside the chains.


IgG purified from human serum


Goat anti-human IgG can also be used for dot blot (1:30,000) and immunohistochemical (1:50) applications.
Serum human IgG levels were analyzed by solid phase ELISA assays using alkaline phosphatase-conjugated goat anti-human IgG antibody incubated for 1 hour at 37°C. Assays was developed using 0.1% p-nitrophenyl phosphate (Sigma) as the substrate. Antibodies to the Seoul (strain 80/39) virus was detected in human sera by western blot analysis using alkaline phosphatase-conjugated goat anti-human IgG antibody at a 1:1000 dilution. Blots were developed using nitroblue tetrazolium and 5-bromo-4-chloro-3-indoyl-phosphate substrate (Sigma).

  1. How does the storage temperature relate to shipping conditions?

    The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. See Shipping and Storage for more information.

  2. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  3. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.
