If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution 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°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

  1. Underexpression of VSNL1 is associated with glioblastoma multiforme. PMID: 26683098
  2. These data indicate that VILIP-1 alone or in combination with other AD CSF biomarkers represent a valuable marker for the early diagnosis of AD, recognition of MCI patients at higher risk to develop dementia, and in differentiating AD from LBD. PMID: 26836160

  11. The findings suggest that CSF VILIP-1 and VILIP-1/Abeta42 predict rates of global cognitive decline similarly to tau and tau/Abeta42, and may be useful CSF surrogates for neurodegeneration in early Alzheimer disease. PMID: 22357717
