| dc.description.abstract | Introduction. The current trend of the management of diseases has shifted toward
modulating the immune response of the patients. This is achieved by the administration
of immunomodulatory substance obtained from the immunogenic medicinal plant, such
as neem. The immunogenic properties of neem has been associated with its protein
content. Aim. This study aimed to characterize the proteins and immunogenic
components of neem leaves juice using sodium dodecyl Sulphate method
Polyacrilamide gel electrophoresis (SDS-PAGE). Materials and Methods. Neem leaf
juice was extracted for proteins with freeze dry method. Samples that were to be run
were added with RSB with the ratio of 1:1, then heated in boiled water for ± 5 minutes.
An amount of 15 µl from each sample was then put into the wells. Samples were run in
120 Volt for 60-80 minutes. Gel was then taken, stained with silver nitrate for 1 hour,
and was then stained every 1.5 hours. Protein bands formed were then observed.
Results. The protein fraction of neem leaves juice consisted of proteins with molecular
weights (MW) as follows: 11 kDa, 13 kDa, 30 kDa, 62 kDa, 70 kDa, 81 kDa.
Conclusion. All protein fractions of neem leaves juice are potentially immunogenic
components. | en_US |
