Background

Three subclasses of IgG can be isolated from the serum of camelids. Conventional IgG1 contains molecules of ~170KD, which upon reduction yield ~50KD heavy chains and large ~30KD light chains. IgG2 and IgG3 are distinct in that they do not incorporate light chains. The IgG2 contain molecules of ~100KD, which upon reduction yield only heavy chains of ~49KD. The IgG3 contain molecules of ~90KD, which upon reduction yield only heavy chains of ~46KD.
Alpaca IgG2 (TKPA105) is an isotype control antibody, which can be used as negative controls to help differentiate non-specific background signal from specific antibody signal.

Storage

This antibody can be stored at 2°C-8°C for one month without detectable loss of activity. Antibody products are stable for twelve months from date of receipt when stored at -20°C to -80°C. Aliquot and store at -20°C to -80°C. Avoid repeated freezing and thawing cycles.
