Potency is the purity of the compound ;this states % available of the main component without water and residual solvents Assay is defined as Potency plus water and residual solvents and other remaining fractions please note assay can also be expressed as as is basis or dry basis Assay and Potency are same if assay is exprtessed as as is basis please note Potency word is mainly used for Antibiotics and bilogicals courtsey ; CDER , USFDA ; Dr.Uttam Krishna
Potency refers to the strength or effectiveness of a drug, typically measured in terms of its ability to produce a specific effect at a given dose. Assay, on the other hand, is a quantitative measurement of the drug's concentration or purity in a sample, often used to confirm its identity and quality. In essence, potency focuses on efficacy, while assay focuses on measuring the quantity or quality of a drug substance.
Ceftriaxone Sodium BP potency is 99.9 % C18H16N8NA2O7S3.3-1/2 H2O given in reference standard Catlog
Assay on 'as is' basis refers to the composition of a substance including its water content, while assay on 'dried' basis refers to the composition of a substance after removing the water content. Comparing these two types of assays can help in understanding the true chemical composition of a substance excluding the influence of water content.
The potency of the medicine was evident in how quickly it relieved her pain.
Assay is a wonderful young man who is very very bright for his age and is 13 years of age how do i know that well i know him closely!
The main difference between ELISA (enzyme-linked immunosorbent assay) and RIA (radioimmunoassay) is the type of label used for detection. ELISA relies on an enzyme-linked detection system, while RIA uses a radioactive label. This distinction affects the sensitivity, safety, and ease of use of the two assays.
Four point assay refers to an estimate of the potency of a drug by measuring the response it produces in a biological it produces i n abiological preparation

No. Pyrogen testing is a process used by drug manufacturers to see if a vaccine or drug has toxins that might cause a fever.An antibiotic assay is used to determine the potency of the antibiotic.

assay on as is basis includes the sample+water content+residual solvents+others. but assay on as is basis takes water content into account that means weight of the water present in the sample will be added in weighing the sample quantity of API required.

Assay is the quantitative determination of the amount of a component in a sample. Purity is the determination of the impurities in the sample. It can be quantitative, semi-quantitative or qualitative. For example : if you dissolve 4 grams of compound A (with no impurities in it) in 6 grams of water, you get a solution of compound A with 100% purity and 40% assay. From the ICH Guideline Q2A (Validation of Analytical methods) : "- Testing for impurities can be either a quantitative test or a limit test for the impurity in a sample. Either test is intended to accurately reflect the purity characteristics of the sample. [...] - Assay procedures are intended to measure the analyte present in a given sample. In the context of this document, the assay represents a quantitative measurement of the major component(s) in the drug substance."

1. anhydrous means : Means remove the water content & solvent free value calculated in the assay. 2. On dry base : Means remove the loss on dry & solvent free value calculated in the assay
An assay pound is a small standard weight used in assaying bullion, which varies between assayers, but is generally around half a gram.
An assay is a scientific test or analysis used to measure the presence, amount, or activity of a substance or compound in a sample. Assays are commonly used in biology, chemistry, and medicine to study a wide range of biological and chemical processes.
Protein assay is the determination of concentration or total level of protein in a solution.There are various protein assays employed like bradford assay and lowry assay
