Can virtual labs be accessed online and offline?
Last Updated on October 26, 2024 by Zinab Hasssan We’re excited to announce a new feature in PraxiLabs dashboard: Progress Report! Now, you can see how well your students are doing, track their performance in each experiment, and get insights into how they’re doing. “Progress Report” is available on both our Free Plan and Paid Plans. It’ll show you date and time of the trial and how long each student takes to complete an experiment, as well as their grade (if they answer the multiple-choice questions). “Progress Report” will also show you any stages that have been skipped during the experiment, for example, the DNA extraction has 3 stages. The new feature will capture any stages that have been skipped by the student in each attempt. Knowing the number of times the student has asked our lab partner “Oxi” to know the next step and the last step that the student stopped at by the progress report, can help you to identify students who may be struggling with certain steps or who might need more help in order to complete the experiment. You can find “Progress Report” on the right side of the simulation name on the dashboard. We hope …

Discover XTT Assay Virtual Lab Simulation from PraxiLabs
Last Updated on March 9, 2023 by Nourhan Essam The XTT assay is an assay used for cellular metabolic activity measuring as an indicator of cell cytotoxicity, viability and proliferation. XTT assay stands for (2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide) which is a tetrazolium-based compound. XTT is a colorless or slightly yellow compound and becomes brightly orange when reduced. In this article we will explain XTT assay experiment virtual lab from PaxiLabs in detail, to understand the XTT assay protocol, principle, procedures, the results and the importance of the experiment. Before talking about the XTT assay experiment from PraxiLabs. Let’s talk an overview about cytotoxicity Cytotoxicity is the toxicity caused by the chemotherapeutic agent’s action on living cells. Cytotoxicity can be caused by the drug itself, such as through the disruption of DNA synthesis, repair or transcription; or by its breakdown products or metabolites. Cytotoxicity tests are very important specifically in nanoparticles because they help in the determination of the proposed biomedical use. Cytotoxicity refers to the amount of damage a chemotherapeutic agent causes to cells. There are many methods involved for cytotoxicity and cell viability determination like: Dyes that used to differentiate the various cells depending on the colors (based on the color uptake ratio …

Your Step by Step Guide to Find Valence Electrons
Last Updated on May 15, 2023 by Sara Assem When you’re reading a scientific text, or having a science lesson regarding bonding and valency, you may come across the term valence electrons. But what does it mean? This is what we will know in this article in detail. In addition to explaining how to find valence electrons in more than one way and explaining a set of examples for further understanding. What are Valence Electrons? To understand how to find valence electrons well, you should learn first what are valence electrons and the following definitions: Valence is the number of electrons an atom should gain or lose to reach the nearest inert gas electron configuration (noble gas). Valence electrons are the outermost electrons in an atom (located in the atom outer shell) and they describe how stable the atom is. Really, valence electrons represent how many electrons are located in an atom’s outermost energy level. They also help in the process of chemical bonds formation and the atom interactions. We can simply define valency as the electrons (or negatively charged particles) that are found in the atom outer shells and are not filled. The number of electrons present in the …

Separating Mixtures| Learn How to Get Fresh Water From Sea Water
Last Updated on December 20, 2022 by Nourhan Essam Have you ever thought about how we can get fresh water from sea water? Or how can we get the skim milk? Or how is blood separated into its four components in hospitals and blood banks? Sand and water/ Cereal and milk/ Sugar and salt/ Salt and water/ Water and ethanol/ Water and pepper/ Cement/ Blood, all of these are examples of mixtures that can be separated by physical methods. We can find many examples of mixtures around us in our daily life. In this article, we will discuss mixtures and separating mixtures techniques. What is Meant by Mixtures? Mixtures are materials that consist of 2 or more substances which don’t combine or mix together by the chemical methods (no chemical reactions happen between the components). Any matter that is not a mixture is a pure matter. If you look around, you will find many mixtures everywhere, like the air we breathe, our earth, the ground and the water of oceans, sea and rivers. The air is a mixture of gasses like oxygen, CO2, nitrogen and more. While the water of the sea and oceans are mixtures of salt, natural water …

Top 10 Microbiology Techniques You Can’t Miss
Last Updated on December 9, 2024 by Ahmed Samy To understand and study the world of microorganisms, we need special techniques or methods that are called “Microbiology techniques”. Microbiology techniques are the methods used for studying microbes (ex: bacteria, fungi and protest). The purpose of these techniques include microbial identification, staining, engineering, survey, culturing and manipulation. What are Microbiological Techniques? Microbiology lab techniques refers to the set of procedures used to study and examine the characteristics of microbes for many scientific purposes. The most common microbiology lab techniques are: Aseptic techniques Staining techniques Culturing techniques Isolation techniques Differentiation techniques Microbiological Techniques examples Now we will mention some of microbiological techniques examples: 1. Microbiology Aseptic Techniques The main importance of aseptic techniques in microbiology is creating suitable controlled conditions to prevent or at least reduce the contamination from other microbes (that entering unsterile sources like water or air or dust) as much as possible so we can grow and study specific microorganisms. Examples of microbiology aseptic techniques used in laboratories: Sterilization Sterilization is used to remove all other forms of microbial organisms like bacteria, viruses, fungus, spores, and other vegetative cells from the culture or the surface of the media.
