Immunofluorescence (IF) Experiment Service

Instruction manual

First Edition (Revised on April, 2016)


Immunofluorescence is a detecting technique based on the specific binding of antigen and antibody, together with the fluorescence microscopy technique. The fluorescence-labeled antibody or antigen specifically binds to corresponding antigen (target protein) or antibody in the sample, and then, fluorescein emits different colors of emissive light after excitation by light of special wavelength. By analyzing the collected emissive light, various data could be obtained, such as the specific location of target protein, concentration of the protein, and interaction of different proteins, etc.
Cloud-Clone Crop. can provide one-stop service for part or the whole of immunofluorescence experiments, such as the preparation of antigen and antibody, fluorescence labeling, treatment of tissue and cell line, fluorescence microscopic observation and photographing, etc.

content of service

1. Preparation of antigen or antibody.
2. Preparation of the positive samples (including cell culture, cell stimulation, animal models, etc.).
3. Fluorescence labeling of antigen or antibody.
4. Preparation of adherent cells, tissue sections, paraffin sections, etc.

Sample requirement

1. Frozen sections, paraffin sections, or cells cultured in 6-well plates or cell culture dish (Detailed technical solutions need to be provided for preparation of special samples, infectious samples have to be marked).
2. Embedding and sectioning services for fresh tissue could be provided by Cloud-Clone Corp. The tissue or specimen from surgery should be fixed in a short time, to avoid autolysis, antigen degeneration, etc.
3. Samples can be customized from Cloud-Clone Corp. (Including cell culture, cell stimulation, animal models, tissue preparation etc.).
