As the solvent travels up the plate‚ the original spot of the compound is moves over. The very polar silica gel tries to hold the spot in its original place and the solvent tries to move the spot along with it as it travels up through the plate. Different components in the original spot with different polarities will move different distances from the original

of siling labuyo and malunggay leaves. The results obtained relied on differential solubilities and adsorptivities of the components to be separated with respect to the mobile and stationary phases‚ wherein the stationary phase/s are silica gel and silica gel G‚ while the mobile phase/s are the extracts on different solvent system. INTRODUCTION This experiment aims to make the students capable of separating the colored components of siling labuyo and malunggay leaves using column chromatography

yogurt are Lactobacillus bulgaricus and Streptococcus thermophilus. The function of the starter cultures is to ferment lactose (milk sugar) to produce lactic acid. The increase in lactic acid decreases pH and causes the milk to clot‚ or form the soft gel that is characteristic of yogurt. The fermentation of lactose also produces the flavor compounds that are characteristic of yogurt. Lactobacillus bulgaricus and Streptococcus thermophilus are the only 2 cultures required by law (CFR) to be present in

IMMUNOCHEMICAL TECHNIQUES: Immunochemistry is an advanced area of immunology. It deals with the chemical components and chemistry (chemical reactions) of immunological phenomena that is of antibody and antigen. Immunochemical methods are processes utilizing the highly specific affinity of an antibody for its antigen. It detects the distribution of a given protein or antigen in tissues or cells. The methods used for the immunochemical analysis are called Immunochemical techniques. Characteristics/Advantages
