- Description of Target:
- Multifunctional redox sensitive protein with various roles in different cellular compartments. In the nucleus is one of the major chromatin-associated non-histone proteins and acts as a DNA chaperone involved in replication, transcription, chromatin remodeling, V(D)J recombination, DNA repair and genome stability. Proposed to be an universal biosensor for nucleic acids. Promotes host inflammatory response to sterile and infectious signals and is involved in the coordination and integration of innate and adaptive immune responses. In the cytoplasm functions as sensor and/or chaperone for immunogenic nucleic acids implicating the activation of TLR9-mediated immune responses, and mediates autophagy. Acts as danger associated molecular pattern (DAMP) molecule that amplifies immune responses during tissue injury.

- Kit Principle:
- Aviva Systems Biology HMGB1 ELISA Kit (Rat) (OKCD04073) is based on standard sandwich enzyme-linked immuno-sorbent assay technology. An antibody specific for HMGB1 has been pre-coated onto a 96-well plate (12 x 8 Well Strips). Standards or test samples are added to the wells, incubated and removed. A biotinylated detector antibody specific for HMGB1 is added, incubated and followed by washing. Avidin-Peroxidase Conjugate is then added, incubated and unbound conjugate is washed away. An enzymatic reaction is produced through the addition of TMB substrate which is catalyzed by HRP generating a blue color product that changes to yellow after adding acidic stop solution. The density of yellow coloration read by absorbance at 450 nm is quantitatively proportional to the amount of sample HMGB1 captured in the well.

- Assay Info:
- Assay Methodology: Quantitative Sandwich ELISA
- Tips Information:
- Sample: Rat serum
- Sample preparation: Serum was previously prepared and frozen at -80C. For 1:100 fold dilution, I added 10 uL of test sample to 990 uL of Standard Diluent as suggested.
- Were these samples validated or characterized as positive and/or negative controls? HMGB1 is a protein ubiquitously expressed in the nuclei of mammalian cells. There are several reports measuring HMGB1 levels in rat serum, plasma, CSF samples (Kim et al., J Neurosci. 2006; 26(24):6413-21; Lee et al., Mol Brain. 2016; 9(1):81; Wang et al., Sci Rep. 2017; 7:46243; Kim et al., Cell Death Dis. 2018; 9(4):426). Thus, it was expected to detect HMGB1 in my samples.
- What dilution worked for your samples? From my previous experience with ELISA, I decided to use undiluted serum and 1:100 fold dilution. I observed that dilution 1:100 resulted in higher HMGB1 levels than undiluted serum.
