Research notes

  • Combine with module neighbors to test non-redundant roles of IFNAR1.
  • Pair phospho/phenotypic readouts with stimulation and inhibitor controls.
  • Validate antibody clone and compartment; include KD/KO controls.

Assay readouts for IFNAR1

  • Receptor–JAK co-IP; ligand dependence.
  • Pair p-STAT downstream readouts.
  • Distinguish γc vs gp130 family context.
  • Primary immune cells vs tool lines.

IFNAR1 experimental notes

Examples below reflect common literature and public resources (e.g., CCLE, DepMap)—validate genotypes, expression, and passage in your own stocks before committing assays.

[1] Cell lines commonly used for IFNAR1 studies (examples)

  • Tool lines: Jurkat, TF-1, Ba/F3, HEK293T, HepG2—screen by IFNAR1 expression (CCLE/DepMap).
  • Combine with neighbors (IFNAR2, IFNGR1, IFNGR2) via KD/pharmacology.
  • Overexpression/rescue in HEK293T supports mechanism and IP.
  • Isogenic/CRISPR models separate dependency from bypass.

[2] Cell samples for IFNAR1 Western blot

  • Whole-cell lysates; phosphatase inhibitors for phospho blots.
  • Optimize stimulation time courses per ligand/stress.
  • Controls: KD/KO or inhibitors.
  • BCA normalization; subcellular fractionation when needed.

[3] Tissue samples for IFNAR1 Western blot

  • Matched tumor/adjacent frozen tissues.
  • Mouse models—mind species cross-reactivity.
  • Primary cells/PDCs when approved.
  • FFPE needs specialized extraction; frozen preferred for phospho.

[4] Cell samples for IFNAR1 immunoprecipitation

  • Tagged overexpression: HEK293T FLAG/HA-IFNAR1.
  • Endogenous IP: high-expression lines.
  • Stimulation enriches interactions.
  • Controls: isotype IgG, empty vector, KO.

Human tissues and primary cells require ethics/IRB approval; tumors are heterogeneous—record histotype, site, and preservation conditions.

Models & genetics note

Overexpression vs endogenous IFNAR1 can differ in dosage, splicing, and compartmentation.
