Immunoglobulin G (IgG), is one of the most abundant proteins in human serum with normal levels between 8-17 mg/mL in adult blood. IgG is important for our defense against microorganisms and the molecules are produced by B lymphocytes as a part of our adaptive immune response. The IgG molecule has two separate functions; to bind to the pathogen that elicited the response and to recruit other cells and molecules to destroy the antigen. The variability of the IgG pool is generated by somatic recombination and the number of specificities in an individual at a given time point is estimated to be 1011 variants.
Secondary & Control Antibodies
Research Sub Category
Whole Immunoglobulin Secondary Antibodies
Routinely evaluated by IP/WB as a non-specific IgG control.
Immunoprecipitation/Western Blot Assay:
2 µg of this lot was used as a non-specific IgG control in an immunoprecipitation / western blot assay.
Purified rabbit polyclonal IgG in buffer containing 0.1 M Tris-glycine, pH 7.4, 0.15 M NaCl, with 0.05% sodium azide before the addition of glycerol to 30%. Liquid at –20°C.
Storage and Stability
Stable for 1 year at -20°C from date of receipt.
For maximum recovery of product centrifuge the original vial prior to removing the cap. Handling Recommendations: Upon first thaw, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variabillity in freezer temperatures below -20°C may cause glycerol containing solutions to become frozen during storage.
