New Video Posted: How to Calculate the Gradient (m) and Intercept (c) in y = mx + c | Gel Analysis Tutorial

This video is in response to a question I have received on YouTube:

“Thanks it is very helpful but can you present how to calculate slope and intercept in this curve”

The question often gets asked about two of my other videos:

• How to calculate the size of a DNA band on a gel?
• How to Determine Protein Size on an SDS-PAGE Gel | Step-by-Step Tutorial

In the How to Calculate the Gradient (m) and Intercept (c) in y = mx + c | Gel Analysis Tutorial, I explain how to calculate the gradient (m) and intercept (c) in the linear equation y = mx + c. I explain three methods that can be used:

1. Graph-based calculation
2. Solving simultaneous equations
3. Using Excel or Apple Numbers.

In the video, I use DNA gel data to illustrate these calculations.
