OspB Antikörper

Produktnummer ABIN964721

Produktdetails

Target: OspB

Reaktivität: Borrelia burgdorferi

Wirt: Kaninchen

Klonalität: Polyklonal

Applikation: Western Blotting (WB)

Spezifität: This product was Protein-A purified and cross-adsorbed against MBP from monospecific antiserum by chromatography. This antibody is specific for Borrelia burgdorferi OspB protein. A BLAST analysis was used to suggest cross-reactivity with OspB from B. burgdorferi, afzelii, spielmanii, and garinii sources based on 100% homology with the immunizing sequence, and with B. valaisiana based on 99% homology. Cross-reactivity with OspB from other sources has not been determined.

Produktmerkmale: OspB, is one of the major Outer Surface Proteins of the outer membrane of Borrelia burgdorferi, which is composed of various unique outer surface proteins (Osp) that have been characterized (OspA through OspF). The Osp proteins are lipoproteins anchored by N-terminally attached fatty acid molecules to the membrane. They are presumed to play a role in virulence, transmission, or survival in the tick. Two of the major surface Ag of Borrelia burgdorferi, the 31-kDa OspA and 34-kDa OspB proteins, show a high degree of sequence similarity, are encoded by a 49-kb plasmid and share a common promoter, and are coordinately transcribed. OspA, OspB, and OspD are expressed by B. burgdorferi residing in the gut of unfed ticks, suggesting that they promote the persistence of the spirochete in ticks between blood meals. OspB has a contributing role in the adherence of B. burgdorferi to the tick gut. B. burgdorferi has the ability to vary its surface proteins in response to immune attack.

Handhabung

Format: Liquid

Konzentration: 1.1 mg/mL

Buffer: 0.02 M Potassium Phosphate, 0.15 M Sodium Chloride, pH 7.2

Konservierungsmittel: Sodium azide

Vorsichtsmaßnahmen: This product contains sodium azide: a POISONOUS AND HAZARDOUS SUBSTANCE which should be handled by trained staff only.

Handhabung: This vial contains a relatively low volume of reagent (25 µL). To minimize loss of volume dilute 1:10 by adding 225 µL of the buffer stated above directly to the vial. Recap, mix thoroughly and briefly centrifuge to collect the volume at the bottom of the vial. Use this intermediate dilution when calculating final dilutions as recommended below.

Lagerung: -20 °C

Informationen zur Lagerung: Store vial at -20° C or below prior to opening. Store the vial at -20°C or below after dilution. Avoid cycles of freezing and thawing.

Haltbarkeit: 3 months
