Description
PA007161: In Vivo Grade Recombinant Mouse IgG3 Isotype Control Antibody
Mouse IgG antibodies are classified to four subclasses mainly based on the isotype of the heavy chain (IgG1, IgG2a or IgG2c, IgG2b, and IgG3 for the heavy chain; kappa and lamda for the light chain), of which IgG1 and kappa are the most abundantnamed in serum. IgG antibodies are large molecules of about 150 kDa composed of four peptide chains, two identical heavy chains of about 50 kDa and two identical light chains of about 25 kDa. The four peptides are arranged in a Y-shape tetramer by disulfide bonds formed between the two heavy chains and between a heavy chain and a light chain.
Questions and Answers:
Question: What is the advantage of the recombinant antibody production method compared to the hybridoma method?
Answer: We use chemically defined medium for cell culturing to produce the recombinant antibody. There is significant advantage of the in vitro method. First, we do not use mouse ascites for antibody production. Second, although antibodies can be produced by cell culturing from over 90% of hybridomas, there is a finite and significant failure rate. The recombinant method can be of help. Third, some companies and scientists add FBS into hybridoma cell culturing medium, which results in antibody contamination. There is no such contamination in production of recombinant antibodies with the chemically defined medium. Fourth, we can easily switch the isotype with different antibody constant regions, and generate mutations which is used in therapeutic antibody research. It is better to use the same isotype control mutation as the primary antibody in the application.
Question: What is an isotype control antibody and why is it used?
Answer: An ideal isotype control matches the isotype of the primary antibody used in the application but lacks binding to the target. It is normally used as a negative control to differentiate, if there is any, non-specific background signal from the specific antibody signal. Mouse IgG1 kappa isotype controls against KLH, TNP, DNP, GST, HEL, His-tag, Flag, c-myc, HA, and GFP meet the requirements in some cases but do not in specific cases in the presence of the targets or cross-reactivity.
