Adriana,
This can be done with very few changes from the above protocol.
Use the same cell density specified, but instead of staining after step 7, leave the medium in the apical chambers. (Do not take apart the system.) Simply read the plate as normal; GFP and calcein AM have similar spectra.
You can gather kinetic data from time zero in this manner, if you wish.
A useful reference is the specific product's guidelines for use, available on our website.

hello , I want to know how many cell lines can be performed in BD matrigel invasion assay chamber of 24 well plate . As i am working in 5 carcinoma cell line including the HT1080 . kindly help me how to perform this assay i have gone through the protocol and the vedio am doing for the first time . thank you

Thank you for watching.
If you are referring to cell lines in general, I would advise you to try any lines you think may be invasive. If you mean can you try five different cell lines on one insert system (plate), you could easily do that with n=3 (replicates per cell line), and still get useful data.

Hello jeff
After the staining procedure in matrigel invasion chamber assay .How to identify the invaded cells and migrated cells as in control and test .After staining the cells are stained as pale red and red colur want to know how to count them.

Stella,
Please see our website for information about the Matrigel Invasion Chamber. The focus of this article is FluoroBlok. In general, the systems are similar, but there are some differences that I cannot detail here.

Hello Jeff As am doing the manual matrigel invasion chamber assay not the fluoroblok one, so i want to know is the cell count will be same as that u g et in fluoroblok . Please help in this issue.

Stella,
The trends will be similar, but the measurement systems are different: clear inserts are measured by visual counting of cells while FluoroBlok is measured using fluorescence detection.

I would like to perform a similar assay using neutrophils. This is to demonstrate anti-inflammation activity of some of my plant extracts. Is the matrigel necessary for my type of experiments? Or do you have inserts without the matrigel

Our microplate reader is not inside of our cell culture room. Due to safety restrictions, we cannon take cells out of our room. Is it possible to add Formaldehyde 4% during the post-labeling step without affecting/compromising the membranes? I know formaldehyde is used to do fluorescence readings, but we want to make sure we wont damage the results by adding them into the Calcein solution.

Hi,
I am interested in doing this assay in 96-well plates. The procedure to be followed would be same except for the amount of volume the wells can hold. So the cell suspension volume, chemoattractant and calcien volume to be prepared and aliquoted to indiviual wells may vary from that of 24-well plates. Can you please give the dimensions of 96-well plates, apical chamber.
Thanks

Hi,
Thanks for the email. I have got the cell invasion kit from BD and about to start my experiment. I was looking into the link that you had sent me for the 96-well plate.
1. However, I have got some doubt pertaining to the testing of my novel anti-cancer compounds.
The intention of the experiment is to test the inhibitory potency of cell invasion through HT-1080 cells. When (at what stage) should I introduce the inhibitory compound solution into the apical chamber? (It’s not mentioned in the protocol).
2. On the instrument settings:
I will be measuring the end-point (NOT- real time)
Sensitivity
If this is going to be a low-signal endpoint assay (I am not sure what that means), 100 readings per well may be optimal as per the instrument manual. BUT,
In fluorescence intensity reading, the sample may photo bleach. SO it is recommended to use 10 readings or less. WHAT NUMBER OF READING WOULD BE OPTIMAL FOR THIS ASSAY?
Setting of gain-intensity, which would be optimal, HIGH or LOW.
In the technical bulletein #436, Set up guidelines are not mentioned for FLEX STATION 3 with SoftMax Pro 5, on which I would be doing my measurement. Your advice and suggestion would be very helpful as the instrument manufacture technical support group has nothing to contribute to this.

Rocio-
this is part of the calculation of the % invasion (invasion index). We compare invasion through Matrigel then effectively use migration without Matrigel as the baseline.
thanks adriana
