Article Title: A lipid-binding protein in black-legged tick saliva selectively recognizes Borrelia burgdorferi lipids
doi: 10.64898/2026.05.04.722819
Figure Lengend Snippet: Extracted B. burgdorferi lipids (∼0.7-0.8 nmol total) were spotted on nitrocellulose films, along with spots of palmitoyl oleoyl phosphatidylcholine (POPC) (39 nmol), cholesteryl stearate (47 nmol), 1,2-dipalmitoyl-sn-glycerol (DAG) (80 nmol), and ⍺-galactosyl ceramide (21 nmol). After blocking with bovine serum albumin, films were equilibrated with TULIP2, washed, developed with mouse anti-TULIP2 antibody and horseradish peroxidase-linked anti-mouse IgG, and imaged by chemiluminescence. Spot intensities, quantified by ImageJ, were normalized to B. burgdorferi lipids. Statistical significance (t-test): **, P < 0.005; ***, P< 0.0005; n.s., not significant
Article Snippet: Control samples for the lipid dot blots were selected to contain functional groups representative of the known composition of B. burgdorferi membrane lipids – : 1-palmitoyl-2-oleoylphosphatidylcholine (Avanti), cholesteryl stearate (Sigma), 1,2-dipalmitoylglycerol (Avanti), and ⍺-galactosyl ceramide (Avanti).
Techniques: Blocking Assay
