- Anh Do added an answer:Do you know the easiest way to isolate lymphocytes in lamina propria in an experimental mouse model?I'm doing an experiment about inflammatory bowel disease in mouse models. I performed IHC in murine colonic tissue, and the lamina propria lymphocytes were well stained with the primary antibody. Next, I want to estimate the mRNA and protein levels in lamina propria lymphocytes.
I know there are several ways to isolate lamina propria lymphocytes in mouse models, However, they are very complex and time-consuming. These ways also require much trial and error. In addition, I don't have the reagents necessary for the isolation methods. Do I have to buy all the reagents, or is there another way to source them?
I would like to know the easiest way to isolate LP lymphocytes in mouse model.
Hi Ekaterina Vladimirovna Sidorova, Jon Jo
How do you dissolve 5mM EDTA? And what is the final pH of the EDTA solution used to disrupt epithelial cells?
Thank you very much.Following
- Dmitry B. Kazansky added an answer:Which antibody manufacturer should I choose?I don't have much experience and I need to analyze some cell markers on flow cytometry as CD38 on human lymphocytes. Does anybody know if Biolegend antibodies are a good choice? Or which manufacturer should I choose?We successfully used antibodies from Biolegend. There were no problems. Good choice.Following
- Sergei B Koralov added an answer:Do you have suggestions for a good method to extract lymphocytes from mouse skin for cytokine profile analysis?We are looking to extract CD4+ T cells from diseased mouse skin for lymphocyte analysis. So far the protocols we have tried either yield only ~500 cells from a 1 cm sq of skin (healthy c57Bl/6 mice) or have such a harsh liberase treatment that some markers such as CD4/8 that we need for our FACS analysis are lost and all are rather inconsistent. If anyone has a good protocol we would really appreciate your advice!Hi Prem,
Thanks for the link. Indeed we've considered Dr. Clark's and Dr. Kupper's method and there are certainly advantages to it, I am a bit hesitant to adapt it for our purposes because the extravasation of T cells into the 3D matrices is accompanied by >10x expansion and by significant molecular changes in the cells including upregulation of the activation markers. While the clonality of the cells should not change, I am concerned that the nature of the cells may be quite different - as we are analyzing tumor cells and are also transferring the T lymphocytes into RAG KO and B6 hosts, I am a bit concerned about changes that may take in these cells in the course of extravasation...Following
- Melanie Dimapasoc asked a question:Has anyone used SepMate tubes + Ficoll for PBMC isolation?If so, have you noticed any difference in RBC, monocyte and/or granulocyte contamination, compared to using Ficoll alone? Also, have you noticed any difference in lymphocyte yield between the two procedures? I am running some validation studies to compare the two separation procedures and have been having some issues with contamination and decreased lymphocyte yields over time using SepMate + Ficoll.Following
