The membrane was washed again with PBST three times for 10 minutes duration each time and the appropriate secondary antibody (horseradish peroxidase conjugated) was added and further incubated in room temperature on the tilt table for 1 hour duration (refer to table 4. The blots were then washed as before for three times. Malaysian Mitragyna Speciosa Rosebud the membrane was incubated in chemiluminescent solutions (Supersignal Chemiluminescent
substrates in 1:1 ratio Pierce Rockford IL) for 5 minutes at room temperature. The membrane was placed in a metal cassette and exposed to hyperfilm (Amersham Germany) in the dark room for an appropriate time period and was developed in an automatic developer.
In the early stage of the testing ICH has recommended an approach called standard test battery which includes three core tests as Malaysian Mitragyna Speciosa Rosebud below: i) a test for gene mutation in bacteria (the Ames Test). Chemicals giving positive results in the standard battery tests depending on their intended use may need to be tested more extensively whereas negative results will usually provide a sufficient level of assurance of safety (ICH 1997). Based on the kratom king paypal ICH recommendation for staged genotoxicity assessment gene mutation in bacteria (the Ames test) was the appropriate first test to be performed; however since the leaves of Mitragyna speciosa Korth have Malaysian Mitragyna Speciosa Rosebud long been used by humans an in vitro test using mammalian cells was thought to be more relevant to perform in the current study. In addition the evaluation of genotoxic potential of MSE and MIT at present is for academic purposes and not a regulatory requirement. The mouse lymphoma tk gene mutation assay (MLA) is widely used and an accepted test system for the assessment of mammalian cell gene mutation; it involves assessment of the thymidine kinase (tk) locus using mouse lymphoma L5178Y cells. The kratom drug abuse dallas center capability of MLA to detect the chromosomal mutations is important as mutations play a central role in carcinogenesis (Mitchell et al 1997). The end point of this test evaluating the size of the colony formations determines the type of chromosomal changes induced.

S9-mix for a treatment period of 24 hours. Selection of concentrations and maeng da kratom forum preparation of test solutions The selection of concentration range tests was based on the cytotoxicity data using trypan blue exclusion assay performed as described in the previous chapter
(Chapter 2). The default vehicle solution for MSE and MIT was ethanol.
