These antibodies target a post-translational modification (PTM) on DNA rather than protein. In order to adequately expose the epitope for binding, the DNA needs to be partially denatured. To accomplish this, we use ethanol and HCl. Traditional formaldehyde fixation followed by detergent-based permeabilization methods will not work for these PTMs.
Metabolic processes regulate immune cell function in a process known as immunometabolism, which can be studied using these macrophage and T-cell markers.

We currently have 6 total p53 antibodies reactive to human p53. All of these antibodies except #2524 and #30313 were produced by using the full-length human p53 as the immunogen. We currently have 1 additional total p53 antibody that binds to rodent p53, p53 (D2H9O) Rabbit mAb #32532. Please see below the comments about the epitopes of specific p53 antibodies.The p53 (1C12) Mouse mAb #2524 was produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ser20 of human p53.Our mapping experiments for the p53 (7F5) Rabbit mAb #2527 have found that the epitope lies within the first 50 amino acids of the protein.Past mapping experiments of the p53 Antibody #9282 lots 3 and 4 have found several p53 regions that showed reactivity to this antibody. The most reactive residues lie within the first 100 amino acids of human p53, however, some reactivity was seen with sequences that lie within the DNA binding domain (aa102-292, UniProt ID P04637-1). Later, addi…
Numerous p53 splice variants have been documented in the literature. They arise from alternative splicing of p53 transcripts and result in multiple isoforms. UniProt for the human sequence (UniProt P04637) lists 9 isoforms produced by alternative promoter usage and alternative splicing and there may be more, depending on the model. Some of these splice variants are associated with polymorphisms or mutations of the p53 genes. Isoform 1 (43.6 kDa) is predominant. However isoform 2 (37.8 kDa) and isoform 3 (38.5 kDa) are also well documented. The combination of p53 cleavage and alternative splicing allows for a diverse size-range of p53 proteins, however, the study of p53 degradation has focused largely on the canonical full-length isoform 1. Also note that the proline-rich region of p53 slows the migration of p53 in SDS-PAGE gels, increasing the apparent molecular weight of the p53 isoforms that express it. [see M.P. Khoury and J.C. Bourdon. (2010) Cold Spring Harb Perspect Biol. 2(3):a000927, Review (PMID: …
The immune system is composed of tissues, cells, and molecules whose primary function is to detect, respond to, and eliminate pathogens and transformed cells.
ChIP-seq is a powerful technique that combines ChIP and next-generation sequencing (NGS) to study DNA-protein interactions across the entire genome, but it is only as good as the quality of the antibody used in the ChIP experiment.
SimpleChIP Kits and Antibodies validated in-house by our antibody development scientists correlated to positive and negative control primers.
The Calpain 2 Large Subunit (M-type) Antibody #2539 detects both active and inactive Calpain 2, which migrate at the same size (79-80 kDa). When Calpain 2 is autoproteolytically cleaved at Ser20, it can result in a 78 kDa band. Cleavage of Calpain 2 at serine 20 does not cause it to be activated; Calpain is only activated when it is bound to calcium.

The two dominant bands detected by our TCF4/TCF7L2 antibodies (#2565, #2569, and #2953) represent different splice variants of TCF4/TCF7L2 [see Weise, A. (2010) Nucleic Acids Res 38, 1964-81 (PMID: 20044351; https://pubmed.ncbi.nlm.nih.gov/20044351/)].

CUT&RUN Frequently Asked Questions (FAQs) from Cell Signaling Technology, Inc.
It remains difficult for scientists to predict the long-term health effects of COVID-19, particularly considering its diversity of effects during acute infection. The most severe impacts appear to manifest in tissues with high levels of vascularization (e.g., lungs, heart, kidney, liver), and it is evident that the virus elicits a significant inflammatory response in infected tissues
CST offers a growing portfolio of products for the study of immune checkpoint targets in cancer, including several receptor-ligand pairs.
Learn how CUT&Tag cuts down your chromatin profiling experiment time. You’ll get the same great data with a fraction of the DNA library prep time and improved signal-to-noise.
CUT&Tag delivers quality NGS data even if the signal from the Bioanalyzer or TapeStation System is low and the DNA library yield is low.
