Phase 2 – Agarose Gel Electrophoresis 1. Obtain our four H, E, L, and P labeled micro tubes and place them on ice. 2. Set the micro pipet to 2.0 ul. 3. Transfer 2.0 ul blue dye to each of the four H, E, L, and P micro tubes. 4. Mix the four micro tubes by using this two-step method: * Place each tube briefly on the vortex to get the components to collect at the bottom of the micro tubes * Pulse spin the four micro tubes in the centrifuge to mix all of the components completely. 5.…
4.1 Maintenance and sub-culturing of endophytic fungi The cultures were procured from already maintained repository in laboratory. The maintenance of the cultures involved preparation of Potato dextrose agar (PDA) plates, sub culturing of cultures and long term preservation. 4.1.1 Preparation of PDA (Potato dextrose agar) plates 39g of PDA was dissolved in 1000 ml double distilled water, stirred to mix properly and was transferred into 250 ml Erlenmeyer flasks and autoclaved at 121˚C at 15…
1.4 Effect of Microcrystalline Cellulose (MCC)Type Formula F12 was utilized to study the effect of changing the type of MCC(Avecil PH-101 ) as a carrier material instead of (Avecil PH-102) in F8 on the dissolution behavior of the prepared Zolmitriptan liquisolid ODTs. Although the DT of formula F12 (79 sec.) was greater than F8 (48 sec.) as in Table(18),the dissolution behavior of the formula F12 was faster than F8 as in Table (18) and Figure (48), this difference was non…
INTRODUCTION Chemically and thermodynamically foam is an unstable, dispersed system of entrapment of gaseous molecules in solid or liquid matter. Instability of foam is caused generally due to coalescence, liquid drainage and disproportion of bubbles. Foam being aqueous system can be produced using surfactants available commercially. The types of surfactants used in preparation of aqueous foam influence the foam properties (Eisner et al., 2007; Bhakta and Ruckenstein, 1995). Successful foam…
4.0 INTRODUCTION TO RESULT AND DISCUSSION This chapter covers the result and also the discussion on the experiment of lab scale soap production. All of the findings which are the analysis of pH value, saponification value and moisture content of the formulation soap bar is discussed thoroughly throughout the chapter. 4.1 RESULT AND DISCUSSION The purposes of the experiment were to identify the weights of materials to be used in the formulation of soap and also to produce the average quality…
Experiment 1 and 2 Recrystallization: Purification of Solids and Melting points Purpose: In the fist experiment, impure Vanillin was purified through the process of recrystallization. Desired solutes were recovered through the technique of vacuum filtration, and then dried to take percent recovery In the second experiment, a percent recovery of the recrystallized Vanillin from the first experiment was performed. The percent recovery of Vanillin was 77.18% A mixed…
According to R.A Aitken, “An asymmetric synthesis may be defined as a synthesis in which an achiral unit is an ensemble of substrate molecules is converted to a chiral unit such that the possible stereoisomers are formed in unequal amounts.” It relates to any synthetic process that incorporates one or more new elements of chirality during a functional group transformation. Asymmetric synthesis involves the formation of chiral molecules. An object is said to be chiral, if it cannot be…
TRIS Hcl, NBT, NADH, Ethanol, PMS, l-ascorbic acid 1. The superoxide radicals is generated in 3 ml of TrisHCl buffer (16 mM, pH 8.0) containing 1 ml of NBT (50 μM), 1 ml NADH (78 μM) and ethanol extract of sample (25 – 50 μg). 2. The reaction was started by adding 1 ml of PMS solution (10 μM) to the mixture. 3. The reaction mixture was incubated at 25° C for 5 min, the absorbance was read at 560 nm using a spectrophotometer (Schimadzu UV-Vis 1700) against blank samples using l- ascorbic acid…
nonmetal materials. Chemical vapor deposition can be defined as the deposition of a solid on a heated surface from a chemical reaction in the vapor phase [2]. Chemical vapor deposition belongs to the class of vapor-transfer processes. Differ from physical vapor deposition, CVD process includes chemical reactions. In the process, gaseous material change in to solid which means the process is…
