IgG or Immunoglobulin G is the most abundant Ig isotype in serum and makes up approximately 80% of all serum Immunoglobulins. In humans, there are four subclasses of IgG with highest serum concentrations of IgG1 followed by IgG2, IgG3 and IgG4.
The measured IgG antibody level in fluids is generally considered to be indicative of an individual's immune status to particular pathogens. Measurement of IgG levels is a means of assessing immunity to measles, mumps, and rubella (MMR), hepatitis B virus, varicella (chickenpox) and many more challenges to the immune system.
Measurement of IgG levels is of great interest to immunologists and pharmaceutical researchers. Fitzgerald Industries offers a wide range of IgG ELISA kits for the rapid and specific quantification of IgG immunoglobulins. We offer a range of species-specific IgG ELISAs such as:
This IgG ELISA has a detection range of 0.15 ug/ml-150 ug/ml and sensitivity of 0.075 ug/ml and is compatible with serum, plasma, cell culture supernates, urine, tissue homogenates, and cell lysates.
This ELISA kit can detect mouse IgG at levels of 125 ng/ml-8000 ng/ml and is sensitive to 125 ng/ml. It works excellently with serum, plasma, cell culture supernates, urine, and tissue homogenates.
The bovine ELISA has a detection range of 9.4 ug/ml-600 ug/ml and sensitivity of 4.7 ug/ml. Compatible sample types for determinging bovine IgG in this kit are serum, plasma, cell culture supernates and tissue homogenates.
Our rat IgG ELISA kit can detect ranges of IgG at 31.25 ng/ml-8000 ng/ml and is sensitivity to rat IgG at levels of 31.25 ng/ml. Samples of serum, plasma, and tissue homogenates can be used with this ELISA kit.
