Antigen HPV-18
Lot Number A10P2E71-001
Method validated Unfolding Profile
Positive Control ABIN457548

Passed. ABIN457548 showed a clear unfolding profile with two detected unfolding events with Tis at 78.4°C and 84.4°C. It is not unusual for antibodies to show more than one unfolding transition, as they are composed of distinct domains that may unfold independently and at different temperatures. This result suggests that the protein is properly folded and functional.

Primary Antibody ABIN457548
  • Dilute ABIN457548 1:10 in PBS buffer (Roth, 1058.1, lot 285231988) to get a final volume of 15µl at a concentration of 0.67µM.
  • Load sample into Tycho capillary (NanoTemper Technologies, TY-C001).
  • Run Tycho measurement.
Experimental Notes

Tycho is designed to run quick and precise protein quality check experiments. Tycho uses intrinsic protein fluorescence to follow protein unfolding while running a fast thermal ramp, yielding results in 3min. A protein’s unfolding behavior is characterized by various parameters, most notably the inflection temperature (Ti). The Ti can be used to identify properly folded protein, to compare different batches, or to analyze the influence of storage/transport conditions on a protein. An absence of Ti would suggest that the protein is already unfolded and therefore most likely nonfunctional.

Background Human papillomaviruses(HPV) are small DNA viruses whichinfect epithelia of the skin and mucosa. Over 90 types have been identified andthey mostly cause a variety of benign lesions such as warts and verrucae.However, some subtypes, notably types 16 and 18, 31 and 33, have been confirmedas agents which cause cervical cancer. Human Papillomavirus (HPV) E7 proteins havecellular transforming and trans-activating activities
Application Notes ELISA:1: 2 000, WB: 1: 1000. This antibody does not work in IP. Monoclonal antibody working titer has to be established practically for each particular antigen and assay format
