Run CSF on HuProt array
Follow the general HuProt microarray protocol.
Protocol-specific parameters:
- For Steps 1, 19, and 21, the secondary antibodies are:
- AlexaFluor 647-cinjugated AffiniPure F(ab')2 Fragment Goat-Antihuman IgG (Catalog number: 109-606-098) Alexa Fluor® 647 AffiniPure™ F(ab)₂ Fragment Goat Anti-Human IgG, Fcγ fragment specificJackson ImmunoResearch Laboratories, Inc.Catalog #109-606-098
- Cy3-conjugated AffiniPure Goat-Antihuman Serum IgA (Catalog number: 109-165-011) Cy™3 AffiniPure™ Goat Anti-Human Serum IgA, α chain specificJackson ImmunoResearch Laboratories, Inc.Catalog #109-165-011
- For Steps 2 and 4, the sample is 1 mL CSF
- NOTE for Step 9, Never allow HuProt microarray slides to dry out during this protocol until drying step.
