IgG Deficiencies

An IgG deficiency is a health problem in which your body doesn't make enough Immunoglobulin G (IgG) People with IgG deficiency are more likely to get infections IgG deficiencies can occur at any age When your body feels it is under attack it makes special proteins called immunoglobulins or antibodies These antibodies are made by B cells

Here we further develop an iDEP device to study the dielectrophoretic behavior of proteins namely bovine serum albumin (BSA) and immunoglobulin G (IgG) molecules in DC mode In contrast to previous studies [ 46 ] we observe the influence of protein aggregation on DEP behavior and downscale the size of the post arrays to sizes smaller than 20

Isolation of immunoglobulin G from bovine milk whey by

Bovine milk whey contains several bioactive proteins such as α‐lactalbumin β‐lactoglobulin and immunoglobulin G (I gG) Chromatographic separation of these proteins has received much attention in the past few years In this work we provide a chromatographic method for the efficient isolation of I gG from bovine milk whey using a poly

Identification and Quantification of Whey Immunoglobulins

Bovine colostrum is often used as the source of Igs as it contains 50 mg mL-1 of Igs whereas milk has only 0 6 mg mL-1 About 80% of Igs in milk or colostrum were of the IgG class (Jenness 1988) Separation of Immunoglobulins by High Performance Liquid Chromatography (HPLC) Samples of the four dialyzed solution (Igs separated from whey)

Comparative studies of two types of bovine immunoglobulin
