Purpose of serial dilution in serology
WebFeb 22, 2024 · A dilution factor is often used, which indicates the factor by which the stock is diluted. Serial dilutions are commonly used to avoid having to transfer a very small volume to make a highly ... WebSerial dilutions are often performed in steps of 10 or 100. They are described as ratios of the initial and final concentrations. For example, a 1:10 dilution is a mixture of one part of a solution and nine parts fresh solvent. For a 1:100 dilution, one part of the solution is mixed with 99 parts new solvent.

After the results are measured, a standard curve from the serial dilutions data is plotted with a concentration on the x-axis using a log scale and absorbance on the y-axis using a linear scale. There are four major types of ELISA:
WebA common practice in immunoassay is the use of sequential dilutions of an initial stock solution of the antigen of interest to obtain standard samples in a desired concentration … WebTiter (American English) or titre (British English) is a way of expressing concentration. Titer testing employs serial dilution to obtain approximate quantitative information from an analytical procedure that inherently only evaluates as positive or negative. The titre corresponds to the highest dilution factor that still yields a positive reading.
WebApr 1, 2024 · The quantitative parameters of bacteriophage-based qPCR detection were first tested by using serial 10-fold dilutions of purified DNA from brucellaphage S708. These experiments were done in three separate runs, each in duplicate, and yielded a log linear function between DNA concentrations and threshold cycle number (Ct), spanning a 9-log … WebThe effect is measured by a suitable test protocol. Serial dilutions of the patient serum are used and the highest dilution where the serum can still prevent complement activity in the indicator system is taken as the CFT titer of the sample. The tests are usually carried out on microtiter plates and the results are observed by eye.
WebA serial dilution is the stepwise dilution of a substance in solution.Usually the dilution factor at each step is constant, resulting in a geometric progression of the concentration in a logarithmic fashion.
