Use of Fourier‐Transform Infrared Spectroscopy to Quantify Immunoglobulin G Concentrations in Alpaca Serum

Background Rapid, economical, and quantitative assays for measurement of camelid serum immunoglobulin G (IgG) are limited. In camelids, failure of transfer of maternal immunoglobulins has a reported prevalence of up to 20.5%. An accurate method for quantifying serum IgG concentrations is required. Objective To develop an infrared spectroscopy‐based assay for measurement of alpaca serum IgG and compare its performance to the reference standard...
