Rabbit Anti-Borrelia burgdorferi sensu stricto (B31) Erpd/Arp37 Antibody

$197.75$1,004.40 excl. VAT

Rabbit Anti-Borrelia burgdorferi Erpd/Arp37 antibody is a polyclonal recognising Borrelia burgdorferi sensu stricto. The antibody is suitable for use in ELISA and Western blotting applications.


This is a polyclonal antibody, prepared against ErpD (OspE/F-Related Protein D), also known as Arp37, from the spirochete B. burgdorferi, for use in ELISA and western blotting applications.



  • Rabbit anti-B. burgdorferi sensu stricto ErpD/Arp37 polyclonal IgG antibody (strain B31).
  • Greater than 95% purity by SDS-PAGE and buffered in 0.02 M Potassium Phosphate, 0.15 M Sodium Chloride, pH 7.2.



Strain B31 is the type strain (ATCC 35210) for this organism and was derived by limited dilutional cloning from the original Lyme-disease tick isolate obtained by A. Barbour (Johnson, et al., 1984). Several studies have demonstrated that infected humans and animals produce antibodies directed against Erp proteins within the first 2-4 weeks of infection, suggesting Erp synthesis occurs during the initial stages of vertebrate infection. Surface-exposed Erp proteins may then facilitate interactions with host tissues during the establishment of vertebrate infection (Fraser, et al., 1997).

Erp proteins from B. burgdorferi are believed to be lipoproteins, based on their predicted amino acid sequences. The spirochete migrates from the tick midgut during feeding to its salivary glands and are thus transmitted to the mammal host. This transition may be facilitated by changes in expression of some B. burgdorferi genes. It is believed that expression of the various proteins associated with the spirochete may be regulated by the changes in tick life cycle, changes in conditions during tick feeding (such as temperature, pH, and nutrients) and/or in coordination with the course of infection of the mammal host (Stevenson, et al., 1996).

Western Blot showing detection of 0.1µg recombinant ErpD/Arp37 protein in western blot. Lane 1: Molecular weight markers. Lane 2: MBP-ErpD/Arp37 fusion proteins (arrow: expected MW of major band: 73.3 kDa). Lane 3: MBP alone. Protein was run on a 4-20% gel, then transferred to 0.45 µm nitrocellulose. After blocking with 1% BSA-TTBS overnight at 4°C, primary antibody was used at 1:1000 at room temperature for 30 min. HRP-conjugated Goat-Anti-Rabbit secondary antibody was used at 1:40,000 in HiGlo Blocking Buffer and imaged on the VersaDoc™ MP 4000 imaging system (Bio-Rad).
