What is the difference between inter-assay and intra-assay variability in laboratory testing methods?
Inter-assay variability refers to differences in results between different tests, while intra-assay variability refers to variations within the same test.
What is the intra-assay coefficient of variation for this particular experiment?
The intra-assay coefficient of variation for this experiment is a measure of the variability within the same assay or test, indicating how consistent the results are.
If the mitochondrion is fundmental to the mtt assay which organelle plays a key role in the neutral red viability assay and why?
The lysosome plays a key role in the neutral red viability assay. Neutral red is taken up by lysosomes and accumulates in these acidic organelles in viable cells, producing a red color. This assay measures lysosomal function as an indicator of cell viability and health.
What is the intact PTH assay used for?
The assay for intact PTH and the N-terminal fragment, which are both measured at the same time, is more accurate in detecting sudden changes in the PTH level. For this reason, the N-terminal PTH assay is used to monitor a patient's response to therapy.
What methods are commonly used for protein concentration measurement in laboratory settings?
Common methods for protein concentration measurement in laboratory settings include spectrophotometry, Bradford assay, BCA assay, and Lowry assay. These methods involve measuring the absorbance of proteins at specific wavelengths or using colorimetric assays to quantify protein levels.
What is the lal assay and how does it work?
The LAL assay, or Limulus Amebocyte Lysate assay, is a test used to detect endotoxins, which are toxic substances released from the cell walls of gram-negative bacteria. It utilizes lysate derived from the blood cells of the horseshoe crab (Limulus polyphemus), which coagulates in the presence of endotoxins. When a sample is introduced to the lysate, the presence of endotoxins activates a cascade of reactions that leads to gel formation, indicating a positive result. This assay is widely used in pharmaceuticals and medical device industries to ensure product safety.
The Lal in Lal Bal Pal was?
The 'Lal' in 'Lal, Bal. Pal' refers to Jawahar Lal Nehru.
What is protein assay?
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
Injectable drugs are tested for endotoxins by?
performing a Limulus Amebocyte Lysate (LAL) test, which detects the presence of endotoxins in the drug product. This test involves lysing amebocyte cells found in the blood of horseshoe crabs, which then interact with endotoxins to produce a gel clot formation, indicating the presence of endotoxins. The LAL test is a sensitive and specific method for ensuring that injectable drugs are free from harmful endotoxins that could cause adverse reactions in patients.
Is assay by mass balance equivalent to assay by as is basis?
No, assay by mass balance and assay by as is basis are not equivalent. Assay by mass balance calculates the amount of a component based on material balance equations, while assay by as is basis measures the amount of a component without accounting for any changes or losses that may occur during processing.
When was Bihari Lal born?
Lal Bihari was born in 1961.
When did Lal Bokhari die?
Lal Bokhari died in 1959.
How do you verify gold bar assay certificate?
You can't verify assay certificates.
Who is better mohan lal or mamootty?
mohan lal
What does 'lal lal' mean?
All mixed up.
When was Lal Pahare'r Katha created?
Lal Pahare'r Katha was created in 2007.
What is the population of Lal Parsa?
The population of Lal Parsa is approximately 10,000 people.
