Experimental Protocol: Sample Preparation 1. Adherent Cells: Place a clean, sterile coverslip in a culture dish. Once the cells grow to near confluence as a monolayer, remove the coverslip for further use. 2. Suspension Cells: Seed the cells onto a clean, sterile slide coated with poly-L-lysine. 3. Frozen Sections: Allow the slide to thaw at room temperature. Wash it with pure water or PBS for 2 times, 3 minutes each time. 4. Paraffin Sections: Deparaffinization and rehydration. Wash the slide with pure water or PBS for 3 times, 3 minutes each time. Then perform antigen retrieval. Fixation 1. Fix the cell coverslips/spots or tissue sections at room temperature using a fixative such as 4% paraformaldehyde (4% PFA) for 10-15 minutes. 2. Wash the sample with PBS for 3 times, 3 minutes each time. Permeabilization 1.Add a detergent such as 0.1–0.3% Triton X-100 to the sample and incubate at room temperature for 10–20 minutes. (Note: This step is only required for intracellular antigens. For antigens expressed on the cell membrane, this step is unnecessary.) Wash the sample with PBS for 3 times, 3 minutes each time. Blocking Add blocking solution and incubate at room temperature for at least 1 hour. (Common blocking solutions include: serum from the same source as the secondary antibody, BSA, or goat serum.) Note: Ensure the sample remains moist during and after the blocking step to prevent drying, which can lead to high background. Immunofluorescence Staining (Day 1) 1. Remove the blocking solution and add the diluted primary antibody. 2. Incubate the sample in a humidified chamber at 4°C overnight. Immunofluorescence Staining (Day 2) 1. Remove the primary antibody and wash with PBST for 3 times, 5 minutes each time. 2. Add the diluted fluorescent secondary antibody and incubate in the dark at 4°C for 1–2 hours. 3. Remove the secondary antibody and wash with PBST for 3 times, 5 minutes each time. 4. Add diluted DAPI and incubate at room temperature in the dark for 5–10 minutes. 5. Wash with PBST for 3 times, 5 minutes each time. Mounting 1. Mount the sample with an anti-fade mounting medium. 2. Allow the slide to dry at room temperature overnight in the dark. 3. Store the slide in a slide storage box at 4°C, protected from light.

生物学的記述

Specificity
Mre11 mAb recognizes endogenous levels of total Mre11 protein.

Clone
K5H6

Background
Mre11 is a highly conserved nuclease and a core component of the Mre11-Rad50-Nbs1 (MRN) complex, which is essential for DNA double-strand break (DSB) repair, telomere maintenance, and genome stability. Structurally, Mre11 functions as a homodimer with a nuclease domain containing five conserved phosphoesterase motifs that coordinate metal ions for its Mn²⁺ -dependent 3′-to-5′ exonuclease and ssDNA endonuclease activities. It is ubiquitously expressed across all domains of life, forming a complex with Rad50 and Nbs1 in eukaryotes to facilitate DNA end processing, homologous recombination, and DNA damage checkpoint activation via ATM kinase. Mre11's role in DNA repair and genomic stability has significant implications for cancer research, chromosomal instability disorders like ataxia telangiectasia-like disorder (ATLD), and potential therapeutic strategies targeting DNA repair pathways.
