Primary Antibodies

Primary Antibodies

Our Primary Antibodies are research-use antibodies designed to support protein detection and target analysis across a wide range of applications and species. Our collection includes recombinant antibodies, monoclonal antibodies, and polyclonal antibodies for use in Western blotting (WB), immunohistochemistry (IHC), immunocytochemistry (ICC), immunofluorescence (IF), flow cytometry (FC), ELISA, and other common applications.

These primary antibodies are available for targets involved in cancer research, immunology, neuroscience, cell biology, metabolism, apoptosis, signaling pathways, and disease-related research. Bioss offers primary antibodies guaranteed for use in human, mouse, rat, and other species to help researchers choose the right antibody format for their experimental model and detection method.

Western blot was performed on whole cell (25 \u00b5g, lane 1) and histone extracts (15 \u00b5g, lane 2) from HeLa cells, and on 1 \u00b5g of recombinant histone H2A, H2B, H3 and H4 (lane 3, 4, 5 and 6, respectively) using the Bioss antibody against H3K9me3 (Cat. No. bs-53114R). The antibody was diluted 1:1,000 in TBS-Tween containing 5% skimmed milk.
HeLa cells were stained with the Bioss antibody against H3K9me3 (bs-53114R) and with DAPI. Cells were fixed with 4% formaldehyde for 10\u2019 and blocked with PBS\/TX-100 containing 5% normal goat serum and 1% BSA. The cells were immunofluorescently labeled with the H3K9me3 antibody (middle) diluted 1:1,000 in blocking solution followed by an anti-rabbit antibody conjugated to Alexa488. The left panel shows staining of the nuclei with DAPI. A merge of both stainings is shown on the right.
To determine the titer of the antibody, an ELISA was performed using a serial dilution of the antibody directed against human H3K9me3 (bs-53114R) in antigen-coated wells. The antigen used was a peptide containing the histone modification of interest. By plotting the absorbance against the antibody dilution, the titer of the antibody was estimated to be 1:30,000.
A Dot Blot analysis was performed to test the cross-reactivity of the antibody against H3K9me3 (Cat. No. bs-53114R) with peptides containing other modifications and unmodified sequences of histone H3 and H4. One hundred to 0.2 pmol of the peptide containing the respective histone modification were spotted on a membrane. The antibody was used at a dilution of 1:20,000. The figure shows a high specificity of the antibody for the modification of interest.
