  • Application Examples
  • Western blot using anti-DNA photolyase (E.coli) antibodies

    Samples: Purified E.coli photolyase 8.4 ng (1), Purified E.coli photolyase 42 ng (2), E. coli crude lysate, 40 μg (3) were separated on 12.5 % SDS-PAGE and transferred to a PVDF membrane at 15V, overnight, followed by blocking with 5 % non-fat milk, washes and incubation with a primary antibodies at 1: 1000 dilution 1h/RT in TBS-T, washes and incubation with secondary antibodies HRP conjugated. Reaction was visualized by chemiluminescnce following manufacture's recommendations.

    Important note: 

    there are only 10-20 molecules of photolyase per E.coli cell, therefore high protein load/well is necessary.

    Immunoprecipitation using anti-DNA photolyase (E.coli) antibodies

    Immunoprecipitation was performed by using Dynabeads Magnetic system (Thermo Fisher).
    Samples: E. coli AB1157 cell lysate (300μg) , primary antibody 2μg (1),   E. coli AB1157 cell lysate (300μg), antibody 10 μg (2), Positve control: E. coli Photolyase purified, 4.2 μg, antibody 10 μg (3), Negative control: No sample, antibody 10 μg (4). Western blot: Anti-Photolyase antibody used at 1 : 1000 dilution and as the second antibody, HRP-conjugated goat anti-rabbit IgG for IP (suitable for detection of immunprecipitation products) was used at 1: 1000 dilution 1 h/RT. Reaction was visualized by chemiluminescence, following manufacture's recommendations.

  • Background
  • Background: Cyclobutane Pyrimidine Dimer photolyase (Deoxyribodipyrimidine photo-lyase) is involved in repair of UV radiation-induced DNA damage. Catalyzes the light-dependent monomerization (300-600 nm) of cyclobutyl pyrimidine dimers (in cis-syn configuration), which are formed between adjacent bases on the same DNA strand upon exposure to ultraviolet radiation. Upon absorption of visible light electrons are transferred from Trp-307 through Trp-360 to Trp 383, and from there to FADH, giving rise to the fully reduced catalytic FADH .
