Disease
Zellweger spectrum disorders, ACOX1 deficiency and DBP deficiency.
Description
Immunofluorescence catalase is used to determine whether catalase import-competent peroxisomes are present and have a normal morphology. In Zellweger spectrum disorders catalase staining is generally cytosolic. Peroxisomal morphology can be also abnormal in Zellweger spectrum disorders and a subset of peroxisomal fatty acid oxidation defects (i.e. ACOX1 deficiency and DBP deficiency).

€ 1055 for full biochemical peroxisomal screening in cultured fibroblasts.
Materials:
Cultured skin fibroblasts
- Conditions: Room temperature.
- Specifics: Grow the fibroblasts to near confluence (~ 80% confluent) in a T-25 flask, fill the flask completely with sterile buffered (with 25mM Hepes) culture medium (for example HAM or DMEM) supplemented with 10% serum and 1% penicilline-streptomycine. Cap the flasks tightly and wrap the cap with parafilm. Label the flask clearly with identifying information (name of patient and date of birth), wrap the culture flaks in protective material and place it in a sealed plastic bag in the Styrofoam shipping box and ship AT ROOM TEMPERATURE by courier service. Fibroblasts need to arrive in our laboratory within 48 hours. Please complete the test request form and send it along with the sample.
If it is not possible to culture fibroblasts from a skin biopsy in a local institute, you can send a skin biopsy in sterile buffered (with 25mM Hepes) culture medium (for example HAM or DMEM) without serum or antibiotics AT ROOM TEMPERATURE by courier service. The skin biopsy needs to arrive in our laboratory within 48 hours. Please complete the test request form and send it along with the sample. - TAT: 3 months.
