Thermo Fisher, R21115, ALA Disk

Name: ALA Disk
Brand: Thermo Fisher
SKU: R21115

Quantity: 25 Disks/Vial, Unit Size: Each, Rapidly differentiate Haemophilus species on the basis of the detection of porphyrin synthesis using Thermo Scientific™ Remel™ ALA Disk. In 1974, Kilian described a rapid method for identification of X-factor independent Haemophilus spp. based on the ability to synthesize heme precursors from ALA^1. Lund and Blazevic determined the porphyrin test is more rapid and accurate for identification of X-factor-independent strains of Haemophilus (e.g. H. parainf

Description

Quantity: 25 Disks/Vial
Unit Size: Each
Members of the genus Haemophilus are small non-motile Gram-negative bacilli traditionally defined by a requirement for X and/or V factor^3. X factor is derived from hemoglobin and V factor through the satellite relationship with Staphylococcus aureus.Rapidly differentiate Haemophilus species on the basis of their detection of porphyrin synthesis using ALA Disk.
• Ready to use:Reagent-impregnated disk
• Rapid test:Results are obtained within a few hours.
• Accurate test:For detection of porphyrins which are only excreted by X-factor-independentHaemophilusspp.
• Easy to identify:A positive result showcases bright yellow fluorescence under long wave ultraviolet light.After incubation the disk is exposed to long wave ultraviolet light in a dark room for any indication of fluorescence. Biberstein et al. studied the action of Haemophilus on δ-aminolevulinic acid (ALA) and reported a perfect correlation between X-factor-independence and the ability to convert ALA to porphyrins^4.Not all products are available for sale in all territories. Please inquire.Remel™ and Oxoid™ products are now part of the Thermo Scientific brand.
