If a powdered form is preferred we do offer comparable alternatives such as 11691112001 from Roche, Human Genomic DNA from human blood (buffy coat). It is not from human placenta but prepared from 100 to 200 individual blood donors of both sexes (pool of the buffy coat). If the DNA from another species is compatible in your application, products D1626 (from salmon) or D6898 (from herring) are options to consider.
