Bloodstains present on pieces of white cotton cloth were exposed to cyanoacrylate ester and then subjected to one of the three light sources at different wavelengths. Although length of exposure to light sources varied, the light source was always 17.5 centimeters from the treated bloodstain. The potential effect of cyanoacrylate ester on RFLP analysis of DNA was determined by exposure of dried bloodstains to superglue vapors. Bloodstain analysis revealed that an RFLP profile using the polymorphic probe MS1 (locus D1S7) could be generated successfully after exposure of bloodstains to cyanoacrylate ester. This observation has relevance in examining objects for fingerprints which also have blood on their surfaces. 8 references, 6 tables, and 3 figures
