Materials and methods 5. Cell lines HEK 293 MCL-5 and SH-SY5Y cells were used. These cell lines were cultured and maintained as described in chapter 2 section 2. Annexin V conjugate staining kit 7-Amino-actinomycin D (7-AAD) dye and HEPES buffer were obtained from Invitrogen U.
However one hypothesis that could be proposed is the possibility of the membrane integrity being compromised especially at high dose of treatment or in other words the lost of cell content through membrane opening. In principle in DNA cycle analysis the movement of DNA profiles to the right side kratom psychoactive herbs of the scale indicates more dye has been taken up. This would be the implication if the pores of the plasma membrane open or if there was a mechanism in which the dyes could diffuse more easily into the cell. Another flow cytometry analysis was carried out in this chapter this time using double staining with Annexin V conjugates-7-AAD to further determine the nature of cell death. Surprisingly this time a similar outcome was observed for both SH-SY5Y and MCL-5 cells and the shifting of the whole populations was evident at much lower concentrations of MSE than in the previous PI staining in Best Kratom Liquid chapter 2. This phenomenon is obviously due to the treatment effects as the control and lowest concentration of the MSE tested as seen in fig. The hypothesis of plasma membrane opening is supported with this finding.
It is proposed that despite taking up the trypan blue dye the cells were still alive but may not be fully functional. It is speculated that one effect of the MSE treatment could be opening of membrane pores to allow the dyes to get in without proceeding to cell death. However at higher dose of MSE dye uptake is more likely to represent cell death.
Ten kratom borneo red vein wirkung elbert thousand cells were analysed by CellQuest Pro software and the subG1 population representing apoptotic cells were gated manually. Reactive oxygen species (ROS) what is the strongest kratom capsules manville analysis in SH-SY5Y cells treated with MSE and MIT ROS generation assay was carried out using SH-SY5Y cells by using a fluorescent dye 27-dichlorofluorescein diacetate (DCFH-DA). Principally this dye diffuses through the cell membrane and is hydrolysed enzymatically by intracellular esterases to form monofluorescent dichlorofluorescein (DCFH) in the presence of ROS. The intensity of the fluorescence is therefore proportional to the levels of intracellular ROS (Galvano et al 2002). A fluorescence-based method to measure ROS generation in live cells was a modification of the procedure described by Esposti and McLennan (1998). This is to ensure that the free-radical quencher albumin present in the serum used as a media supplement is removed as it interferes with the quantitative analysis of ROS (Esposti 2002). M) under subdued lighting.

P53 levels of MIT treated SH-SY5Y cells at different time points (6 12 24 and 48 hr). Effects of MSE and MIT on p53 target gene product p21 It is well established that induction of p53 can lead to expression of malaysian kratom characteristics huron target gene p21 and thereby cell cycle arrest.
