The 5-HIAA antibody was raised to 5-HIAA coupled to BSA with paraformaldehyde. The antibody produces moderate labeling of raphe neurons in normal rat. In rats whose serotonergic system has been activated, staining intensity is increased to a maximum label. Recommended dilutions of the antiserum are 1/200-1/400 for indirect immunofluorescence and 1/4000-1/8000 for biotin-streptavidin/HRP technique. The specificity of the antiserum was evaluated using a model system of gelatin-indole plugs by a method similar to published procedures (Schipper and Tilders, 1983). Results showed that the 5-HIAA antibody dose dependently stained 5-HIAA but did not stain any concentration of 5-HT or 5-HTP. The antiserum was also tested by pre-adsorption at 25 µg/mL with various BSA conjugates. While pre-adsorption with 5-HIAA conjugate completely eliminates immunolabeling, pre-adsorption with conjugates of 5-HT,5-HTP and dopamine had no effect on staining intensity or distribution of stain.
5-hmC | 5-hydroxymethylcytosine is a recently discovered DNA modification which results from the enzymatic conversion of 5-methylcytosine into 5-hydroxymethylcytosine by the TET family of oxygenases. It may have an important roles distinct from that of 5-methylcytosine (5-mC). 5-hmC bases have been identified in Purkinje neurons, in granule cells and embryonic stem cells where they are present at high levels (up to 0,6% of total nucleotides in Purkinje cells.

The 5-HT Antibody was raised in rabbit against 5-HTP coupled to BSA with paraformaldehyde. The antibody has a proven maximum biotin-streptavidin/HRP staining at a 1/1000 - 1/2000 dilution in rat raphe nuclei. Optimal dilution will vary depending upon fixation, labeling technique and/or detection system; therefore, a dilution series is recommended. The specificity of the antiserum was evaluated using a model system of gelatin-indole plugs by a method similar to published procedures (Shipper and Tilders, 1983). Results showed that the 5-HTP antibody dose dependently stained 5-HTP but did not stain any concentration of 5-HT or 5-HIAA. The antiserum was also tested by pre-adsorption with indole/paraformaldehyde/BSA conjugates. Staining was completely blocked by pre-adsorption with 5-HTP conjugate and unaffected by 5-HIAA or 5-HT conjugate.

The 5-HT 5A Receptor Antibody was raised against synthetic peptide sequence corresponding to amino acids 17-34 of the rat 5-HT5A receptor coupled to carrier protein with glutaraldehyde. The ImmunoStar 5-HT5A Receptor was quality control tested using standard immunohisto-chemical methods. The antiserum demonstrates strongly positive labeling of rat cortex and hippocampus using indirect immunofluorescent and biotin/avidin-HRP techniques. Recommended primary dilutions are 1/100 - 1/300 in PBS/0.3% Triton X-100Â - Cy3 and 1/200Â - 1/400 in PBS/0.3% Triton X-100Â - Bn/Av-HRP. Intensification methods such as nickel will approximately double the dilution factor as recommended. The antibody was characterized by immunoblotting and immunohistochemistry. Immunoblots of rat brain extracts revealed the presence of two bands at molecular weights of 41 and 47 kD.

DNA methylation is a type of chemical modification of DNA that can be inherited and subsequently removed without changing the original DNA sequence. Therefore it is part of the epigenetic code and is also the most well characterized epigenetic mechanism. DNA methylation results in addition of a methyl group to DNA — for example, to the number 5 carbon of the cytosine pyrimidine ring — which involves reduction in gene expression. In adult somatic tissues, DNA methylation typically occurs in a CpG dinucleotide context; non-CpG methylation is prevalent in embryonic stem cells.

5-methylcytosine (5-mC) is formed from the DNA methylation of the 5-carbon found on the cytosine ring. A 5-methylcytosine monoclonal antibody is a useful tool in identifying and discriminating between the unmodified cytosine base (C) and the methylated cytosine base (5-mC) as part of DNA methylation studies. DNA methylation plays an important role in the repression of transcription in the genome. When present in promoter regions, 5-mC is associated with stable transcriptional silencing which results in inactivation of gene function, thereby having an important role in tumorigenesis.
