IgG1-Fc Recombinant Human Protein

Immunoglobulin gamma-1 heavy chain constant region, partial (IgG1-Fc), recombinant human protein is supplied as a lyophilized powder. In general, recombinant proteins can be used as protein standard and in cell biology research applications.

This recombinant human protein is expressed from a DNA sequence encoding the human IgG1-Fc region (AAC82527.1), containing residues 99 to 330, including a 103 Cys/Ser mutation.

N-terminal Sequence Analysis: Glu 99.

Activity:
1. Measured by its ability to bind human CD16a-His (Cat:10389-H08H1) in a functional ELISA.
2. Measured by its ability to bind human CD16a-AVI-His (Cat:10389-H27H) in a functional ELISA.
3.Measured by its ability to bind human CD16a-His (Cat:10389-H08H) in a functional ELISA.

Formulation: lyophilized in PBS, pH 7.4, 5% mannitol, 5% trehalose, and 0.02% Tween®-80.

Reconstitution: Dissolve the protein in sterile double-distilled water to a concentration of 0.2 mg/mL or lower. It is recommended that the protein be aliquoted and used as soon as possible. Store aliquots under sterile conditions at -20°C. Avoid repeated freeze-thaw cycles.

Expiration Date: expires one year from date of receipt when stored as instructed.

Background
Immunoglobulin G (IgG) is synthesized and secreted by plasma B cells, and constitutes 75% of serum immunoglobulins in humans. IgG antibodies protect the body against the pathogens by agglutination and immobilization, complement activation, toxin neutralization, as well as the antibody-dependent cell-mediated cytotoxicity (ADCC). Recombinant IgG Fc is suggested to represent a potential anti-inflammatory drug for treatment of human autoimmune diseases.

UltraPure™ BSA (50 mg/mL) Invitrogen™

UltraPure BSA is a non-acetylated bovine serum albumin (BSA) pure enough to use when DNA or RNA integrity is critical. One tube containing 50 mg is provided, at a concentration of 50 mg/mL. BSA has many uses as a carrier protein and as a stabilizing agent in enzymatic reactions. In northern, Southern, and dot blot hybridizations, BSA is also used as a blocking agent. It is recommended in buffers for nick translation, polymerase reactions, and ligations. BSA is also a common additive for PCR amplifications, footprinting, and gel shift assays. In restriction digests, BSA has been shown to enhance enzyme activity. The molecular weight is 68 kD. UltraPure BSA is rigorously tested for DNase, RNase, endonuclease, and protease activity.

Frizzled 4 Recombinant Human Protein Gibco™

Recombinant Frizzled 4 is a bioactive protein intended for use in cell culture applications. FZD4 is a member of the Frizzled family, which are 7-transmembrane domain proteins that are receptors for Wnt signaling proteins. Wnt signaling is involved in several developmental processes.

protein G, horseradish peroxidase conjugate Invitrogen™

The horseradish peroxidase (HRP) conjugate of protein G can be used to detect the Fc portion of various classes and subclasses of immunoglobulins from a variety of species. Protein G is a bacterial protein similar to protein A but with superior selectivity for mouse and human IgG.
