概述

  • 产品名称

    Janus Green cell normalization stain

  • 经测试应用

    适用于: In-Cell ELISAmore details

  • 常规说明

    Ready-to-use green stain for normalizing antibody signal intensity to total cell amounts during in-cell ELISA (ab111622).

    Cells fixed to a solid surface (typically in microplate wells) can be stained by adding 1X Janus Green Stain. Incubate cells for 5 minutes at room temperature. Dye should be removed and washed 5 times in ultrapure water or until excess dye is removed. The last wash should be removed and add 0.1 mL 0.5 M HCl per well and incubate for 10 minutes. Shake the plate for 10 seconds, and measure the OD 595 nm using a standard microplate spectrophotometer.

Question

For this janus green assay, the protocol states to read the plate at 595nM. Can the absorbance of the 0.1 ml HCl solution be read in the same wells the cells were grown or do you recommend spinning down the plate, removing the solution to clean well prior to taking OD measurements?

Answer

Yes, the OD 595 can be read directly on the plate where the cells were grown and the assay was performed. The HCL will disrupt the cells and the janus green (which stains the nuclei) will be released into the well. No need to spin or move the HCL to a different plate.

Question

Dear Sirs,
a customer of ours would like to know which is the right wavelenght to read the signal of Janus Green.

Thanks in advance

Answer

Thank you for your enquiry,

We recommend to measure the assays results at OD595 nm using a standard microplate spectrophotometer. We will be amending the datasheet to make this clearer.

Whole Cell Staining with Janus Green:

1. Completely remove HRP Development Solution from themicroplate wells and blot to dry. Add 50 μl of 1X JanusGreen Stain per well. Incubate plate for 5 minutes atroom temperature.

2. Remove dye, wash plate 5 times in ultrapure water oruntil excess dye is removed.

3. Remove last water wash, blot to dry, add 100 μl of 0.5 MHCl and incubate for 10 minutes.

4. Shake the plate for 10 seconds, and measure the OD595 nm using a standard microplate spectrophotometer

I hope this will be helpful. If you have any further questions, please do not hesitate to contact us.
