Product Specs

Introduction
CD57, also known as B3GAT1, belongs to the glucuronyltransferase gene family. It displays high acceptor specificity, recognizing nonreducing terminal sugars and their anomeric linkages. CD57 participates in the glucuronyl transfer reaction during the biosynthesis of the HNK-1 carbohydrate epitope.
Description
Recombinant Human CD57 protein, expressed in Baculovirus, is a single, glycosylated polypeptide chain comprising 549 amino acids (28-334aa) with a molecular weight of 62.3kDa. This protein is fused to a 239 amino acid hIgG-His-Tag at its C-terminus and purified using proprietary chromatographic methods.
Physical Appearance
Sterile, colorless solution, filtered for purity.
Formulation
The CD57 solution is provided at a concentration of 0.25mg/ml in a buffer consisting of 20mM Tris-HCl (pH 7.5), 10% glycerol, and 0.1M NaCl.
Stability
For short-term storage (2-4 weeks), keep at 4°C. For extended periods, store frozen at -20°C. Adding a carrier protein (0.1% HSA or BSA) is recommended for long-term storage. Avoid repeated freeze-thaw cycles.
Purity
Purity exceeds 90.0% as determined by SDS-PAGE analysis.

Product Science Overview

Expression Patterns and Tissue Distribution

CD57 is present on approximately 15-20% of peripheral blood mononuclear cells (PBMCs), including subsets of NK cells and T cells . It is also expressed on certain neural cell types . The expression of CD57 is increased in some disease states associated with CD4/CD8 imbalances, such as AIDS, autoimmune diseases, viral infections, and allograft transplants .

Biological Functions

While the precise function of CD57 remains unclear, it is known to bind to L-selectin, P-selectin, and a fragment of laminin, suggesting a role in cell-matrix interactions . This binding capability indicates that CD57 may be involved in processes such as cell adhesion and migration.

Modes of Action and Regulatory Mechanisms

The regulatory mechanisms governing CD57 expression and function are not fully understood. However, its increased expression in certain disease states implies that it may play a role in immune response modulation. Further research is needed to elucidate the exact pathways and regulatory factors involved.

Applications in Research

CD57 is commonly used as a marker in immunological research, particularly in studies involving NK cells and T cells. Recombinant antibodies targeting CD57 are utilized in various applications, including flow cytometry, immunofluorescence, and immunohistochemistry . These antibodies are valuable tools for investigating the role of CD57 in health and disease.
