Technical Notes & Calculators

Technical Note #1 - ELISA Assay Validation

Parallelism, linearity-of-dilution and spike-and-recovery experiments are essential validation studies that assess the ability of the ELISA assay to measure the true (ie. accurate) amount of antigen in the sample.

Technical Note #2 - ELISA Data Analysis

Choosing an appropriate non-linear calibration curve regression model is essential for accurate ELISA data analysis, because immunoassays usually do not follow a linear dose-response relationship.

Technical Note #3 - A Guide to Flow Cytometry Experimental Design

Planning a Flow Cytometry experiment requires knowledge about the protein target of interest, the right antibody and appropriate controls.

Technical Note #4 - Acid-Extraction of BDNF From Brain Tissue

Acid-extraction can be used as an alternative tissue extraction method to release BDNF, which can be bound to its receptors and chaperons within many tissues. Samples prepared following this protocol can be assayed for BDNF content by ELISA and also used in Western Blotting to assess BDNF protein expression.

Technical Note #5 - Mature BDNF Isoform Detection and Quantification by ELISA

The detection and quantification of mature BDNF by ELISA poses a challenge due to potential cross-reactivity of the proBDNF full-length isoform. This Technical Note demonstrates our efforts in validating mature BDNF quantification by ELISA, and explores the issues relating to using other immunological techniques for validation of BDNF isoform detection by ELISA assay.
