Interpolated concentration of native IgG1 was measured in duplicate at different sample concentrations. Undiluted samples are 1 : 8,000,000 serum, plasma (EDTA), plasma (citrate), and plasma (heparin). The interpolated dilution factor corrected values (to neat sample) are plotted (mean +/- SD, n=2). Sample dilutions are made in 1X Wash Buffer PT.

Cross reactivity of related immunoglobulin proteins. 50 ng/mL of natively purified human IgG2, IgG3, IgG4, IgA, IgD, IgE, and IgM were tested individually for cross-reactivity. Percent reactivity was determined by interpolating the protein concentration from the human IgG1 standard curve and expressing the interpolated concentration as a percentage of the protein concentration tested.

Product details

Human IgG1 ELISA Kit, Chemiluminescent (ab325732) is a rapid single-wash sandwich 55-min ELISA to measure Human IgG1 in Serum, Plasma – Citrate, Plasma – EDTA, Plasma – Heparin, Cell Culture Media, Urine, Saliva with a sensitivity of 1.18 pg/mL.

How the assay works

Human IgG1 ELISA Kit, Chemiluminescent (ab325732) SimpleStep Ignite™ ELISA employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step during a 30 min only incubation, significantly reducing assay time. By utilizing a chemiluminscent detection method this improves the sensitivity and dynamic range when compared to traditional colorimetric ELISAs.

Assay Specificity

Our SimpleStep Ignite™ ELISA kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

Target data

Constant region of immunoglobulin (Ig) heavy chains. Igs are membrane-bound or secreted glycoproteins produced by B lymphocytes. In the recognition phase of humoral immunity, the membrane-bound Igs serve as receptors, which upon binding to a specific antigen trigger the clonal expansion and differentiation of B lymphocytes into Ig-secreting plasma cells. Secreted Igs known as antibodies mediate the effector phase of humoral immunity by blocking the interaction of infectious antigens with cellular receptors (via the antigen-binding region) and eliciting effector mechanisms that lead to pathogen neutralization (via the constant region) (PubMed : 17576170, PubMed : 20176268, PubMed : 22158414). The antigen-binding region is formed by the variable domain of one heavy chain paired with the variable domain of its associated light chain. Each Ig molecule has two antigen-binding sites with remarkable affinity for a particular antigen due to V-(D)-J rearrangement, somatic hypermutations and affinity maturation of the variable domains upon antigen exposure (PubMed : 17576170, PubMed : 20176268, PubMed : 22158414). The constant region defines the Ig isotype that perform distinct sets of effector functions. B cells diversify and rearrange their Ig constant regions through class-switch recombination, a process by which the constant region is switched from one Ig isotype to another, namely from IgM and IgD to IgG, IgA and IgE (PubMed : 17576170, PubMed : 20176268, PubMed : 22158414). The constant region of Ig gamma-1 (IgG1) isotype interacts (via the fragment crystallizable, Fc) with receptors on innate immune cells and the complement system to mediate humoral effector functions, including antibody-dependent cellular cytotoxicity or phagocytosis, complement-dependent cytotoxicity and inflammatory responses.
