After separation in SDS-PAGE, the proteins were transferred to the Hybond-P membrane (GE Healthcare, Chicago, IL, USA) by semi-dry transfer using the Trans-Blot Turbo Transfer System (Bio-Rad Laboratories, Hercules, CA, USA). To prevent non-specific binding of antibodies, the membrane was incubated in a 5% solution of skimmed dry milk in 10 mM PBS for 1 h with constant stirring. Then, the membrane was incubated with mouse anti-M2e polyclonal antibodies, washed, and then treated with the anti-mouse IgG HRP conjugate (W4021, Promega, Madison, WI, USA). Specific protein complexes were visualized using the Western Blot ECL Plus kit (GE Healthcare).

Complement Pathway Modulation by RaCI2

Check if the same lab product or an alternative is used in the 5 most similar protocols
The effect of RaCI2 on all three pathways was tested using a Wieslab complement system screen (Euro Diagnostica, Sweden) following manufacturer’s instructions. Measurements were subtracted with buffer only and normalised for serum only samples (100% activity). Other classical and alternative pathway assays were carried out as described by A. Roos et al. 42 (link), with the following modifications. 2 μg/ml IgM (Bio-Rad) and 1.8 mg/ml LPS from Salmonella typhosa (Sigma-Aldrich) were used to coat ELISA plates. Human serum was diluted 1/100 (classical pathway) or 1/10 (alternative pathway). MAC deposition was detected with primary antibodies against C5b-9 (aE11, Abcam), and secondary anti-mouse IgG HRP conjugate (Promega). HRP activity was detected with 2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) liquid substrate (Sigma-Aldrich) and the reaction was stopped by adding an equal volume of 1% SDS. The absorption was measured at 405nm. Measurements were subtracted with buffer only samples and normalized for serum only samples (100% activity). The competition assays were performed using size-exclusion purified inhibited C5 complexes (see purification of C5 complexes above) added to the reaction at the concentrations specified.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
