Chromatin immunoprecipitation analysis of Tri-Methyl-Histone H3 (Lys27) was performed using cross-linked chromatin from 1x10^6 HCT116 colon carcinoma cells treated with serum for 0, 15, and 30 minutes. Immunoprecipitation was performed using a multiplex microplate Matrix ChIP assay (see reference for Matrix ChIP protocol: http://www.ncbi.nlm.nih.gov/pubmed/22098709) with 1.0ul/100ul well volume of a Tri-Methyl-Histone H3 (Lys27) monoclonal antibody (Product # MA5-11198). Chromatin aliquots from ~1x10^5 cells were used per ChIP pull-down. Quantitative PCR data were done in quadruplicate using 1ul of eluted DNA in 2ul SYBR real-time PCR reactions containing primers to amplify -20kb upstream of the LAMC1 gene or exon-1 of LAMC1. PCR calibration curves were generated for each primer pair from a dilution series of sheared total genomic DNA. Quantitation of immunoprecipitated chromatin is presented as signal relative to the total amount of input chromatin. Results represent the mean +/- SEM for three experiments. A schematic representation of the LAMC1 locus is shown above the data where boxes represent exons (black boxes = translated regions, white boxes = untranslated regions), the zigzag line represents an intron, and the straight line represents upstream sequence. Regions amplified by LAMC1 primers are represented by black bars. Data courtesy of the Innovators Program.

Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA is wrapped in repeating units, called nucleosomes. The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures. This gene is intronless and encodes a member of the histone H3 family. Transcripts from this gene lack polyA tails but instead contain a palindromic termination element. This gene is found in the large histone gene cluster on chromosome 6.
