Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Plays a role in influencing the retrograde trafficking of lysosomal sorting receptors SORT1 and IGF2R from the endosomes to the trans-Golgi network by controlling the recruitment of retromer complex to the endosomal membrane. Regulates the localization and activation of RAB7A which is required to recruit the retromer complex to the endosomal membrane.
Gene References into Functions
  1. Genotype-phenotype correlation between CNL5 gene mutations and CNL5 disease symptoms. PMID: 28542837
  2. We conclude that, whereas sleep homeostasis is present in CLN5(-/-) sheep, underlying CLN5(-/-) disease processes prevent its full expression, even at early stages. PMID: 27488642
  3. findings support CLN5 hypomorphic mutations cause autosomal recessive cerebellar ataxia, confirming other reports showing CLN mutations are associated with adult-onset neurodegenerative disorders PMID: 25359263
  4. Two forms of CLN5, derived from the C-terminal proteolytic processing, are present in most cells and tissues. PMID: 26342652
  5. There are functional differences in various N-glycosylation sites of CLN5 which affect folding, trafficking, and lysosomal function of CLN5. PMID: 24058541
  6. a role for CLN5 in controlling the itinerary of the lysosomal sorting receptors by regulating retromer recruitment at the endosome PMID: 22431521
  7. This study highlights a close interaction between CLN5/CLN8 proteins, and their role in sphingolipid metabolism. Our findings suggest that CLN5p/CLN8p most likely are positive modulators of CerS1 and/or CerS2. PMID: 23160995
  8. analysis of mutations in neuronal ceroid lipofuscinosis protein CLN5 PMID: 20052765
  9. CLN5 mutations are 1) more common in patients with neuronal ceroid lipofuscinosis (NCL) than previously reported, 2) found in patients of broad ethnic diversity, and 3) can be identified in patients with disease onset in adult and juvenile epochs PMID: 20157158
  10. Study found that CLN5 interacts with several other NCL proteins namely, CLN1/PPT1, CLN2/TPP1, CLN3, CLN6 and CLN8. PMID: 19941651
  11. biosynthesis and intracellular localization of this protein PMID: 11971870
  12. A novel missense mutation in CLN5 was found in a Colombian family with juvenile-onset neuronal ceroid lipofuscinosis: c. 1627G>A causing Arg112His. PMID: 15728307
  13. The CLN5/mRNA expression level reduced to 45% supports the existence of one mRNA non-producing allele, further noticeable at the protein level. PMID: 16814585
  14. Reports two sibs harbouring a novel mutation (p.Tyr258Asp) in the CLN5 gene and displaying behaviour disturbances and mental deterioration, rather than epilepsy, as the dominant disease manifestation at onset. PMID: 17607606
  15. In cultures of brain microvascular endothelial cells, VEGF-A specifically down-regulated CLN-5 and OCLN protein and mRNA PMID: 19174516
  16. Double immunofluorescence microscopy showed that while the wild-type CLN5 protein is localized in lysosomes, both mutant CLN5 proteins are retained in the endoplasmic reticulum rather than reaching the lysosome. PMID: 19309691
