Cell experiment: |
Selected mouse brain samples from either cortical or striatal regions (100 mg wet weight) and neuroblastoma cells (SH-SY5Y) pellet derived from 25 cm2 flask are treated with 500 μL of 0.1 M HCl containing 0.2% TDGA, sonicated for 10 min (only for brain tissue), and then centrifuged at 14000 g for 30 min. The supernatant is freeze-dried. 50 μL of reaction buffer and 100 μL of 15 mM Dabsyl chloride are added to the tube and derivatized. |

Dabsyl chloride is an amine derivatizing agent, able to give rise to stable products that can be easily monitored spectrophotometrically at 460 nm; Dabsyl chloride also used for labeling amino acids.
Dabsyl chloride can give rise to mono-Dabsyl and bis-Dabsyl derivatives in the presence of multiple amino groups. Furthermore with respect to OPA derivatization, Dabsyl chloride can react with primary and also with secondary amines[1].

Reversed-phase high-performance liquid chromatographic analysis of hydroxyproline and proline from collagen by derivatization with Dabsyl chloride
J Chromatogr 1993 Nov 24;621(2):133-8.8294534 10.1016/0378-4347(93)80088-l
A high-performance liquid chromatographic method for the analysis of hydroxyproline and proline has been developed. The method is based on the derivatization of the secondary amino group with dabsyl-chloride after blocking of the primary amino group with o-phthalaldehyde. Dabsyl-hydroxyproline and dabsyl-proline were separated from other amino acids by high-performance liquid chromatography in the gradient elution mode, and eluted at 10.27 and 16.02 min, respectively. The correlations between the peak areas of dabsyl-hydroxyproline and dabsyl-proline were linear in the range from 20-200 pmol, with equations y = 1.10x - 0.80 (r = 0.999) and y = 1.12x - 0.52 (r = 0.999), respectively. The method was applied to the analysis of rat tail collagen, and the contents of hydroxyproline and proline were 1.55 +/- 0.04 and 2.03 +/- 0.04 nmol/micrograms, respectively.
Determination of neomycin in the form of neomycin derivative with Dabsyl chloride by thin layer chromatography and densitometry
Acta Pol Pharm 2015 Jan-Feb;72(1):31-7.25850198
A thin layer chromatographic-densitometric method has been developed for identification and quantitative determination of neomycin derivative with Dabsyl chloride. The analysis of antibiotic was achieved on the silica gel TLC plates with fluorescent indicator with n-butanol--2-butanone--25% ammonia--water (10 : 6 : 2 : 2, v/v/v/v) as the mobile phase. The densitometric measurements were made at 460 nm. Under these conditions good separation of chosen aminoglycoside antibiotic from reagent used to make a complex was obtained. The method is characterized by high sensitivity, LOD from 0.1953 μg per band and LOQ from 0.5918 μg per band, wide linearity range from 0.5918 to 2.1960 μg per band for neomycin. The precision of the method was good; RSD varied from 1.17 to 2.05%. Satisfactory results of validation of the method were also confirmed by determination of selected antibiotic in pharmaceutical commercial preparation. The results obtained by TLC-densitometric method were compared with those obtained by spectrophotometric method.
Visible labeling of proteins for polyacrylamide gel electrophoresis with Dabsyl chloride
Anal Biochem 1984 Aug 15;141(1):121-6.6437269 10.1016/0003-2697(84)90434-2
Several proteins, which are used as molecular weight markers in polyacrylamide gel electrophoresis, were reacted with Dabsyl chloride. This labeled them deep orange and the chromophore attachment was stable throughout the electrophoretic procedure and fixation. Small amounts (10-50 micrograms) of the labeled proteins could be loaded onto gels and seen with the unaided eye so that the separation during electrophoresis could be followed. Dabsylation did not affect the mobility of the proteins. The location of the orange band gave a good indication of the position of the protein in the gel so that molecular weight estimations could be made during and immediately following electrophoresis.

Spectrophotometric determination of bacitracin in bulk drug as dabsyl derivative in a range of visible light
Acta Pol Pharm 2011 Nov-Dec;68(6):853-8.22125949
A fast spectrophotometric method has been developed for bacitracin identification and determination after condensation reaction with Dabsyl chloride. In addition, determination of dye stability of sulfonamide derivative and identification of the molar ratio of reagents was done at various time-points. The developed method has a good linearity with very broad spectrum, correlation coefficient of r = 0.9972, good precision (RSD = 1.54 +/- 0.11%), and recovery at three different levels of concentration was found between 98.33% and 103.47%. Usefulness of the method was demonstrated by positive results obtained during determination of bacitracin concentration in bulk drug.
