Protein A-HRP (Invitrogen™)

Protein A from Staphylococcus aureus, Cowan I Strain conjugated with highly purified horseradish peroxidase (RZ > 3.0).

The product is liquid containing 10 mM phosphate, 0.15 M NaCl buffer, pH 7.4, 1% ovalbumin, 40% glycerol, and 0.19% Kathon CG/ICP.

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 A, Alexa Fluor™ 488 conjugate (Invitrogen™)

Our Alexa Fluor 488 protein A conjugate binds to the Fc portion of various immunoglobulins from several different species. This exceptionally bright, green-fluorescent probe (absorption/emission maxima ~495/519 nm) can be used to visualize antibodies in a manner analogous to a labeled species-specific secondary antibody.

Recombinant Protein G-HRP (Invitrogen™)

Recombinant protein G is produced in a strain of E. coli which contains the gene for protein G from Streptococcus sp. This protein G is conjugated with highly purified horseradish peroxidase (RZ > 3.0) and is in enyme conjugate stabilizer containing 0.19% Kathon CG/ICP.

Recombinant protein G binds to the Fc region of many types of immunoglobulin G including:

• all four subclasses of human IgG
• mouse IgG
• rabbit IgG
• guinea pig IgG
• rat IgG
• goat IgG
• sheep IgG
• cow IgG
• horse IgG

Recombinant protein G does not bind to IgG from chicken or cat, or to human IgA, IgM, or serum albumin. It binds weakly to IgG from dog.

Protein A, Alexa Fluor™ 647 conjugate (Invitrogen™)

Our Alexa Fluor® 647 protein A conjugate binds to the Fc portion of various immunoglobulins from several different species. This exceptionally bright, far red-fluorescent probe (absorption/emission maxima ~650/668 nm) can be used to visualize antibodies in a manner analogous to a labeled species-specific secondary antibody.

Recombinant Protein G (Invitrogen™)

Recombinant protein G is produced in a strain of E. coli which contains the gene for protein G from Streptococcus sp. It is supplied as a salt-free lyophilized powder.

Recombinant protein G binds to the Fc region of many types of immunoglobulin G including:

• all four subclasses of human IgG
• mouse IgG
• rabbit IgG
• guinea pig IgG
• rat IgG
• goat IgG
• sheep IgG
• cow IgG
• horse IgG

Recombinant protein G does not bind to IgG from chicken or cat, or to human IgA, IgM, or serum albumin. It binds weakly to IgG from dog.

Bovine Serum Albumin (Invitrogen™)

Bovine Serum Albumin is suitable for use as an enzyme stabilizer during purification or for dilution of restriction endonucleases and nucleic acid modifying enzymes. BSA is also commonly used in DNA and protein labeling experiments as a blocking agent to minimize background. This BSA is acetylated to inactivate contaminating nucleases and proteases.

Performance and quality testing
Purity is determined by SDS-PAGE. No detectable contaminating activity is observed in 3´ and 5´ exonuclease, DNA nicking, and restriction endonuclease inhibition assays.
