It is important to note that a vaccine is a drug. Like any drug, vaccines have benefits and risks, and even when highly effective, no vaccine is percent effective in preventing disease or percent safe in all individuals.
Most side effects of vaccines are usually minor and short-lived. Vaccination is when a vaccine is administered to you usually by injection. Immunisation is what happens in your body after you have the vaccination. The vaccine stimulates your immune system so that it can recognise the disease and protect you from future infection ie, you become immune to the infection.
This calculation is only for the indigenously prepared Reference std. It is calculated by area normalisation method, it can be directly find out by chromatograms obtained from HPLC. Ur potency calculation is not adequate?????. While Potency of an API is the assay on as is basis………………. M A solution is Equivalent to …….. Is above information correct or wrong?
I am also having a doubt. In Assay formula, used Assay or Potency of standard. So, are Assay and Potency same? For further details refer Water Empower. For Assay calculation : Dried basis is OK but anhydrous basis, Sulphated ash and residual solvent can be minus. I am working for a government regulatory body for pharmaceutical products and this formula always pops up almost automatically everytime when the product being registered has come from India.
Do you have any reputable reference to back up you formula? Why is this methodology only comes from India and also Pakistan? No other country uses this in their product formulation. This is debatable. Hi dear u can see my comment above. You are commenting using your WordPress. Assay and purity are two types of measurements used to determine the components of a sample. Both of them are important aspects of chemistry and biochemistry.
What is an Assay — Definition, Facts, Types 2. An assay is the analysis of a component of a sample. Here, the type of measurement can be either qualitative or quantitative. That means; an assay measures the presence, amount or the functional activity of a component in a sample. In chemistry, an assay is a testing method of a metal or ore to determine its ingredients and quality.
On the contrary, assays are a type of widely used analyzing methods of samples in pharmacology, laboratory medicine, biochemistry, biotechnology, immunology , environmental biology, etc. Here, the analyte or the main target component can be a drug, biochemical substance, a cell of an organism or an organic sample. Figure 1: Samples for a Spectrophotometer Assay. Generally, a fixed amount of exogenous reactants or reagents are added in an assay. Therefore, the target component becomes the only variable factor during the analysis.
Furthermore, the general steps involved in an assay can be:. Moreover, assays can be classified based on different aspects.
