Protein-Typ: Recombinant

Spezies: Human

Quelle: Escherichia coli (E. coli)

Applikation: ELISA, Functional Studies (Func), Blocking Reagent (BR), Intracellular Flow Cytometry (ICFC)

Marke: BD Pharmingen™

Spezifität: Representative Biological Activity: Measured Calcium flux using lysed whole blood. The ED50 for these effects is typically 0.15 - 0.30 µg/ml or 0.1 -0.5 ng/ml respectively.

Produktmerkmale: Purified human IL-8 was found to be > 98% pure as measured by SDS-PAGE analysis and an absorbance assay based on the Beers-Lambert law. Recombinant human IL-8 is a lyophilized aqueous buffered solution containing 50 µg bovine serum albumin per 1µg recombinant human IL-8. The product contains no preservatives.

Reinheit: ≥ 98 %

Sterilität: 0.22 μm filtered

Endotoxin-Niveau: The endotoxin level is ≤ 0.1 ng endotoxin per µg human IL-8 as measured using a chromogenic LAL assay.

Anwendungsinformationen

Applikationshinweise: ELISA Standard: Recombinant human IL-8 is useful as a quantitative standard for measuring human IL-8 protein levels in an IL-8 specific sandwich ELISA with the purified G265-5 antibody (Cat. No. 554716) as a capture antibody and the biotinylated G265-8 (Cat. No. 554718) as the detection antibody. To obtain linear standard curves, doubling dilutions of this human IL-8 standard from 500-4 pg/ml should be included in each ELISA plate.
Note: This ELISA pair is recommended primarily for measuring cytokine from experimental cell culture systems. These ELISA reagents are not recommended for assaying serum or plasma samples. For measuring human IL-8 in serum or plasma the BD OptEIA™ human IL-8 ELISA Set (Cat. No. 555244) and OptEIA™ human IL-8 ELISA Kit (Cat. No. 550999) are specially formulated and recommended.

Ligand Blocking Control for Immunofluorescent Staining of Cytokines: Recombinant human IL-8 can be used as a blocking control to demonstrate specificity of IL-8 staining by the directly conjugated G265-8 antibody (Cat. No. 554720). The intracellular cytokine staining technique and use of blocking controls are described in detail by C. Prussin and D. Metcalfe.
Note: Carrier proteins should be pre-screened for possible effects in an appropriate experimental system. Carrier proteins may effect experimental results due to toxicity, high endotoxin levels or possible blocking activity.

Beschränkungen: Nur für Forschungszwecke einsetzbar

Handhabung

Format: Lyophilized

Konservierungsmittel: Azide free

Handhabung: This preparation contains no preservatives, thus it should be handled under aseptic conditions. Store product at -80°C prior to reconstitution, or for long term storage of stock solutions.The product can be reconstituted in sterile neutral buffer containing carrier protein such as human or bovine serum albumin, aliquoted and stored at -80°C. For in vitro biological assay use, we recommend carrier-protein concentrations of 0.5 -1 mg/ml. For use as an ELISA standard we recommend carrier-protein concentrations of 5 - 10 mg/ml.
Note: Failure to add carrier protein or store at indicated temperatures may result in a loss of activity.

Hintergrund: Interleukin-8 (IL-8) is an 8 kD protein containing 72 amino acid residues. It promotes neutrophil chemotaxis and degranulation. The 72 amino acid IL-8 is the predominant form secreted by monocytes and lymphocytes.
