Efficient immunoaffinity chromatography of lymphocytes directly from whole blood

Immunoaffinity Chromatography: A Review

Affinity chromatography is a high resolution, high capacity, and one of the most powerful and diverse methods for separating proteins and other biological molecules of interest on the basis of a highly specific, reversible biological interaction between two molecules: an affinity ligand attached to a solid matrix to create a stationary phase, and a target molecule in a mobile phase. Specificall...

Isolation and purification of HLA-DR antigen from Daudi cell line by immunoaffinity chromatography

Introduction: The major histocompatibility complex (MHC) is a group of cell surface proteins that are essential for recognizing foreign molecules in human and other mammals. The physiologic function of MHC molecules is the presentation of peptides to T cells. In this study, we evaluated the purification of a class II MHC molecule (HLA-DR) from a human Burkitt′s lymphoma cell line; Daudi...

Integrated acoustic immunoaffinity-capture (IAI) platform for detection of PSA from whole blood samples.

On-chip detection of low abundant protein biomarkers is of interest to enable point-of-care diagnostics. Using a simple form of integration, we have realized an integrated microfluidic platform for the detection of prostate specific antigen (PSA), directly in anti-coagulated whole blood. We combine acoustophoresis-based separation of plasma from undiluted whole blood with a miniaturized immunoa...

Isolation of chitin deacetylase from Mucor rouxii by immunoaffinity chromatography

The purification of chitin deacetylase from Mucor rouxii to homogeneity employing conventional methods has already been described. However, a lengthy protocol is required resulting in a low yield and specific activity for the enzyme . A 169-fold one-step purification of chitin deacetylase by immunoaffinity chromatography is reported, resulting in a homogeneous enzyme preparation. The enzyme pur...
