Major constituent of plaques and tangles that occur in Alzheimer's disease (AD) patients.

Format/Formulation: Lyophilized trifluoroacetate salt

Molecular Weight: 4515

PCSK9/NARC1 Recombinant Human Protein, His Tag

PCSK9/NARC1, recombinant human protein is supplied as a lyophilized powder. It is suitable for use in protein studies such as protein structure analysis and protein-protein interactions. In general, recombinant proteins can also be used as an immunogen, as a protein standard, or in cell biology research applications.

This recombinant protein was expressed from a DNA sequence encoding the human PCSK9 (NP_777596.2) (Met1-Gln692) was expressed with a polyhistidine tag at the C-terminus.

Formulation: Lyophilized from sterile PBS (pH7.4), 5%-8% Mannitol, 5%-8% Trehalose, and 0.01% Tween-80 added prior to lyophilization.

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 be 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.

β Amyloid [1 40] Pure PTD Human Protein (Invitrogen™)

Major constituent of plaques and tangles that occur in Alzheimer's disease (AD) patients.

Format/Formulation: Lyophilized trifluoroacetate salt, >95% purity by HPLC.

Molecular Weight: 4331

Protein A (Invitrogen™)

Protein A purified from Staphylococcus aureus. Lyophilized, salt-free powder; no preservative added. Molecular weight is approximately 42kD.

WNT1 Recombinant Human Protein (Gibco™)

Recombinant Wnt-1 is a bioactive protein intended for use in cell culture applications. Wnt-1 secretion plays an important role in embryonic development and carcinogenesis. Wnt-1 is involved in cell proliferation, patterning, motility, and fate determination. Wnt-1 may also affect morphogenesis of the neural tube and in Central Nervous System (CNS) development.

BGG Stock Solution, acetylated

Invitrogen's Acetylated BGG solution is a 0.5% solution in water. The material is tested for level of background fluorescence.

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.

Rec Protein A (Invitrogen™)

This recombinant protein A from Staphylococcus aureus Cowan I was expressed in Bacillus. The gene has been altered to truncate the protein A at the carboxyl terminal. This does not affect the binding characteristics.

Pierce™ c-Myc Peptide (Thermo Scientific™)

Pierce c-Myc peptide may be used to elute c-Myc-tagged proteins from Thermo Scientific Anti-c-Myc Agarose, when the bound protein is sensitive to conditions of chemical elution, such as extremes in pH, or sodium thiocyanate.

Frizzled 7 Recombinant Human Protein (Gibco™)

Recombinant Human Frizzled-7 (FZD7) is a bioactive recombinant protein intended for use in cell culture applications. FZD7 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.

The protein sequence of Frizzled-7 corresponds to the extracellular region of mature Human Frizzled 7, aa 33-185, fused to the Fc region of Human IgG1.

The equilibrium binding constant, KD, of Human Frizzled 7 was measured at less than 10nM using mouse Wnt3a as the ligand. Measurements were made using the ForteBio Octet optical biosensor instrument.

β Amyloid [1 40] PTD Human Protein (Invitrogen™)

Major constituent of plaques and tangles that occur in Alzheimer's disease (AD) patients.

Format/Formulation: Lyophilized trifluoroacetate salt, >96% purity by HPLC.

Molecular Weight: 4331

Protein G, Alexa Fluor™ 488 conjugate (Invitrogen™)

Alexa Fluor 488 protein G conjugate exhibits bright, green fluorescence (absorption/emission ~495/519 nm). Protein G is a bacterial protein similar to protein A but with superior selectivity for mouse and human IgG.

Bovine Serum Albumin (BSA) (Thermo Scientific™)

Thermo Scientific Bovine Serum Albumin (BSA) is ideal for stabilization of enzymes during storage and for enzymatic reactions where the absence of nucleases is essential. BSA increases PCR yields from low purity templates. It also prevents adhesion of enzymes to the reaction tubes and tip surfaces.

Highlights

• Non-modified (non-acetylated)
• Fraction V

Applications

• Enzyme stabilization
• PCR with low purity templates, e.g. mouse tail DNA
• Restriction enzyme digestion
