推荐实验流程

Bioimaging 1. Seed the cells in appropriate culture medium at ~10,000 cells per well in a BD Falcon™ 96-well Imaging Plate (Cat. No. 353219) and culture overnight. 2. Remove the culture medium from the wells, and fix the cells by adding 100 μl of BD Cytofix™ Fixation Buffer (Cat. No. 554655) to each well. Incubate for 10 minutes at room temperature (RT). 3. Remove the fixative from the wells, and permeabilize the cells using either BD Perm Buffer III, 90% methanol, or Triton™ X-100: a. Add 100 μl of -20°C 90% methanol or Perm Buffer III (Cat. No. 558050) to each well and incubate for 5 minutes at RT. OR b. Add 100 μl of 0.1% Triton™ X-100 to each well and incubate for 5 minutes at RT. 4. Remove the permeabilization buffer, and wash the wells twice with 100 μl of 1× PBS. 5. Remove the PBS, and block the cells by adding 100 μl of BD Pharmingen™ Stain Buffer (FBS) (Cat. No. 554656) to each well. Incubate for 30 minutes at RT. 6. Remove the blocking buffer and add 50 μl of the optimally titrated primary antibody (diluted in Stain Buffer) to each well, and incubate for 1 hour at RT. 7. Remove the primary antibody, and wash the wells three times with 100 μl of 1× PBS. 8. Remove the PBS, and add the second step reagent at its optimally titrated concentration in 50 μl to each well, and incubate in the dark for 1 hour at RT. 9. Remove the second step reagent, and wash the wells three times with 100 μl of 1× PBS. 10. Remove the PBS, and counter-stain the nuclei by adding 200 μl per well of 2 μg/ml Hoechst 33342 (e.g., Sigma-Aldrich Cat. No. B2261) in 1× PBS to each well at least 15 minutes before imaging. 11. View and analyze the cells on an appropriate imaging instrument.

制备与储存

Store undiluted at 4°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.

荧光格式说明

Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.

产品提示

Please refer to www.bdbiosciences.com/us/s/resources for technical protocols., Since applications vary, each investigator should titrate the reagent to obtain optimal results., This antibody has been developed and certified for the bioimaging application. However, a routine bioimaging test is not performed on every lot. Researchers are encouraged to titrate the reagent for optimal performance., Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing., Triton is a trademark of the Dow Chemical Company.

A cytochrome is an electron-transporting protein that contains a heme prosthetic group. Cytochromes have been known to be essential components of the mitochondrial respiratory chain since 1925. The iron atom of the heme group in cytochromes alternates between a reduced ferrous (+2) state and an oxidized ferric (+3) state during electron transport in oxidative phosphorylation. Cytochromes are classified into four groups (a, b, c and d) according to spectrochemical characteristics, and there are five cytochromes between coenzyme QH2 and O2 in the electron transport chain. Cytochrome c is a water-soluble protein that either promotes cell survival or death, depending upon its intracellular location. In healthy cells, it is a peripheral membrane protein of the mitochondria that transports electrons from the coenzyme QH2 cytochrome c reductase complex to the cytochrome c oxidase complex. When proapoptotic stimuli induce breakdown of the mitochondria, cytochrome c is released to the cytosol where it functions in the activation of caspases that trigger apoptosis. The 6H2.B4 monoclonal antibody has been reported to recognize the native and not the denatured form of rat, mouse, and human cytochrome c. Furthermore, studies utilizing competitive ELISA indicate that mAb 6H2.B4 binds to a region around residue 62 of rat cytochrome c. The 6H2.B4 monoclonal antibody is not useful for western blot analysis. For the western blot application, clone 7H8.2C12 (cat.no. 556433) would be recommended. Suggested positive controls for detecting cytochrome c include P388D mouse lymphoma cells (ATCC CCL-46), HeLa human carcinoma cells (ATCC CCL-2), Jurkat T leukemia cells (ATCC TIB-152) and NIH 3T3 mouse fibroblast cells (ATCC CRL-1658). This antibody is routinely tested by immunoprecipitation. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.
