Product listing: Methyl-Histone H3 (Lys9) Antibody Sampler Kit, UniProt ID P68431 #76252 to Mitochondrial Marker Antibody Sampler Kit, UniProt ID X10101 #8674

The Methyl-Histone H3 (Lys9) Antibody Sampler Kit provides an economical means of detecting levels of mono-, di-, and tri-methyl histone H3 Lys9 using methyl-specific and control histone H3 antibodies. The kit contains enough primary antibodies to perform at least two western blot experiments.

Background: The nucleosome, made up of four core histone proteins (H2A, H2B, H3, and H4), is the primary building block of chromatin. Originally thought to function as a static scaffold for DNA packaging, histones have now been shown to be dynamic proteins, undergoing multiple types of post-translational modifications, including acetylation, phosphorylation, methylation, and ubiquitination (1). Histone methylation is a major determinant for the formation of active and inactive regions of the genome and is crucial for the proper programming of the genome during development (2,3). Arginine methylation of histones H3 (Arg2, 17, 26) and H4 (Arg3) promotes transcriptional activation and is mediated by a family of protein arginine methyltransferases (PRMTs), including the co-activators PRMT1 and CARM1 (PRMT4) (4). In contrast, a more diverse set of histone lysine methyltransferases has been identified, all but one of which contain a conserved catalytic SET domain originally identified in the Drosophila Su(var)3-9, Enhancer of zeste, and Trithorax proteins. Lysine methylation occurs primarily on histones H3 (Lys4, 9, 27, 36, 79) and H4 (Lys20) and has been implicated in both transcriptional activation and silencing (4). Methylation of these lysine residues coordinates the recruitment of chromatin modifying enzymes containing methyl-lysine binding modules such as chromodomains (HP1, PRC1), PHD fingers (BPTF, ING2), tudor domains (53BP1), and WD-40 domains (WDR5) (5-8). The discovery of histone demethylases such as PADI4, LSD1, JMJD1, JMJD2, and JHDM1 has shown that methylation is a reversible epigenetic marker (9).

The Microglia Cross Module Antibody Sampler Kit provides an economical means of detecting proteins identified as markers of microglial activity corresponding to proliferation, neurodegeneration, interferon and LPS-relation by western blot and/or immunofluorescence.

Background: Distinct microglial activation states have been identified using RNA-seq data from a vast array of neurological disease and aging models.

ChiP-Grade Protein G Agarose Beads are an affinity matrix for the small-scale isolation of immunocomplexes from chromatin immunoprecipitations (ChIP assays). A truncated form of recombinant Protein G is covalently coupled to agarose beads. Protein G exhibits high affinity for subclasses of IgG from many species (including human, rabbit, mouse, rat and sheep) and can be used for immunoprecipitation assays with these antibodies. The beads are stored in buffer containing BSA (500 µg/ml) and sonicated salmon sperm DNA (200 µg/ml) to block non-specific binding of proteins and DNA during isolation of immunocomplexes. These beads are not compatible with ChIP-seq because the sonicated salmon sperm DNA interferes with downstream sequencing.

ChIP-Grade Protein G Magnetic Beads are an affinity matrix for the small-scale isolation of immunocomplexes from chromatin immunoprecipitation (ChIP) assays. A truncated form of recombinant protein G is covalently coupled to a nonporous paramagnetic particle. Protein G exhibits high affinity for subclasses of IgG from many species (including human, rabbit, mouse, rat and sheep) and can be used for immunoprecipitation assays with these antibodies. The beads are stored in buffer containing BSA (1 mg/ml) to block non-specific binding of proteins and DNA during isolation of immunocomplexes. Beads can be separated from solution using our 6-Tube Magnetic Separation Rack #7017, which concentrates the beads to the side of the tube instead of the bottom. This eliminates centrifugation steps, minimizes sample loss and increases washing efficiency. These beads are compatible with ChIP-seq.

Background: The chromatin immunoprecipitation (ChIP) assay is a powerful and versatile technique used for probing protein-DNA interactions within the natural chromatin context of the cell (1,2). This assay can be used to identify multiple proteins associated with a specific region of the genome, or the opposite, to identify the many regions of the genome bound by a particular protein (3-6). It can be used to determine the specific order of recruitment of various proteins to a gene promoter or to "measure" the relative amount of a particular histone modification across an entire gene locus (3,4). In addition to histone proteins, the ChIP assay can be used to analyze binding of transcription factors and co-factors, DNA replication factors and DNA repair proteins. When performing the ChIP assay, cells or tissues are first fixed with formaldehyde, a reversible protein-DNA cross-linking agent that "preserves" the protein-DNA interactions occurring in the cell (1,2). Cells are lysed and chromatin is harvested and fragmented using either sonication or enzymatic digestion. The chromatin is then immunoprecipitated with antibodies specific to a particular protein or histone modification. Any DNA sequences that are associated with the protein or histone modification of interest will co-precipitate as part of the cross-linked chromatin complex and the relative amount of that DNA sequence will be enriched by the immunoselection process. After immunoprecipitation, the protein-DNA cross-links are reversed and the DNA is purified. Standard PCR or Quantitative Real-Time PCR can be used to measure the amount of enrichment of a particular DNA sequence by a protein-specific immunoprecipitation (1,2). Alternatively, the ChIP assay can be combined with genomic tiling micro-array (ChIP on chip) techniques, high throughput sequencing, or cloning strategies, all of which allow for genome-wide analysis of protein-DNA interactions and histone modifications (5-8).

The Mitochondrial Dynamics Antibody Sampler Kit provides an economical means to examine signaling involved in mitochondrial dynamics. The kit contains enough primary antibody to perform two western blot experiments.

Background: Import of proteins into the mitochondria is regulated by the translocase of the outer mitochondrial membrane (TOM) complex, which facilitates transport through the outer mitochondrial membrane, and a complementary translocase of the inner membrane (TIM) complex, responsible for protein transport to the mitochondrial matrix. The TOM complex consists of the receptors Tom20, Tom22, and Tom70, and the channel-forming protein Tom40 (1). Tom20 is localized in the outer mitochondrial membrane and initially recognizes precursors with a presequence to facilitate protein import across the outer mitochondrial membrane (2).Changes in mitochondrial dynamics regulated by environmental cues affect mitochondrial size and shape and have been shown to dramatically impact mitochondrial metabolism, apoptosis, and autophagy (3). These processes are largely controlled by mitochondrial dynamin-related GTPases, including mitofusin-1, mitofusin-2, OPA1, and DRP1. DRP1 regulates mitochondrial fission, while the mitofusins and OPA1 control fusion at the outer and inner mitochondrial membrane, respectively. These proteins are tightly regulated. OPA1 activity is regulated through alternative splicing and post-translational modifications, including complex proteolytic processing by multiple proteases (4-9). In addition, OPA1 expression can be induced under conditions of metabolic demand through a pathway involving Parkin induced NF-κB activation (10). DRP1 is regulated in part through multiple phosphorylation sites (11). Phosphorylation of DRP1 at Ser616 by MAPK or during mitosis by CDKs stimulates mitochondrial fission (12-14). Mitochondrial fission factor (MFF) is a tail-anchored protein that resides within the outer mitochondrial membrane and is part of the mitochondrial fission complex. MFF participates in mitochondrial fission by serving as one of multiple receptors for the GTPase dynamin-related protein 1 (Drp1) (15-18). AMPK directly phosphorylates MFF at two sites to allow for enhanced recruitment of Drp1 to the mitochondria (19). 

The Mitochondrial Marker Antibody Sampler Kit provides an economical means to evaluate relevant mitochondial proteins. This kit contains enough primary antibody to perform two western blots per primary.
