Competitive ELISA Tutorial 3: Analyzing Typical Competitive ELISA Data in Excel
Просмотров 93 тыс.10 лет назад
In this video, we show how typical data from a Competitive ELISA (Enzyme-Linked Immunosorbent Assay) can be analyzed using common spreadsheet software, such as Microsoft Excel. There are several programs available for the analysis of ELISA data, but Excel is such a common program that it will be beneficial for many people to see how data analysis can be done using this program alone. Here is th...

Gelatin Zymography Tutorial 5: Quantifying MMP Activity with Image J and Normalizing Samples
Просмотров 11 тыс.10 лет назад
Here we demonstrate how to quantify bands of MMP activity in a Gelatin Zymogram using Image J, and then normalize the MMP activity of samples to an MMP-2 standard in Excel. We also explain the rationale behind normalizing samples with an MMP standard, which is to account for the variations which normally occur from gel to gel. Links mentioned in the video: Image J download website - rsbweb.nih....
Gelatin Zymography Tutorial 4: Identifying MMPs by Molecular Weight
Просмотров 10 тыс.10 лет назад
In this video, we demonstrate how to identify which MMPs are detected on a Gelatin Zymogram using a Molecular Weight Protein Ladder. Scanned images of the zymogram before staining are manipulated in PowerPoint in order to identify the molecular weight of the bands of MMP activity that can be observed in the stained zymogram. We also demonstrate how to manipulate the colors of the zymogram in or...

Competitive ELISA Tutorial 1: How a Competitive ELISA Works
Просмотров 248 тыс.10 лет назад
Here, we discuss the concept behind a Competitive ELISA (Enzyme-Linked Immunosorbent Assay). Competitive ELISAs are commonly used to measure the amount of a specific protein, antibody, or metabolite in a given sample. Though Competitive ELISAs may initially be hard to understand, we hope that this brief video will make some essential concepts as easy to understand as possible. Our ELISA tutoria...

  • @user-yv4gn1oe1k
    @user-yv4gn1oe1k Год назад

    That was really helpful. Thank you so much! The problem I am experiencing is that Prism would just "make up" values for the readings that were negative or 0. Even though in one run I had a zero standard given with the absorbance and concentration of zero it would calculate a concentration of 50 for another sample that had the same absorbance?! Any suggestions on how I can prevent this, so that my interpolation will also just not give me any result for the samples at or below 0?
