An erratum was issued for: A High Throughput MHC II Binding Assay for Quantitative Analysis of Peptide Epitopes.  There were typos in the Protocol section and Table 2.

Step 3.1.1 in the Protocol was updated from:

Add 80 µl of 1 mM Pefa Bloc and 60 mg of octyl-β-D-glucopyranaside to 3,920 µl of Citrate Phosphate Buffer. (See supplemental spreadsheet calculator for alternative scaling).

to:

Add 80 µl of 1 mM Pefa Bloc and 60 µg of octyl-β-D-glucopyranaside to 3,920 µl of Citrate Phosphate Buffer. (See supplemental spreadsheet calculator for alternative scaling).

Step 5.2 in the Protocol was updated from:

Further dilute the Control Peptide from step 5.1 (20 mM) 1:100 into the MHC II Master Mix from step 3.2.

to:

Further dilute the Control Peptide from step 5.1 (20 µM) 1:100 into the MHC II Master Mix from step 3.2.

Table 2 was updated from:

MHC II Stock Concentration (mg/ml)1.3
MHC II Stock Concentration (mM)20
Vol. MHC II Stock to Add (ml)14.65
Vol. Reaction Buffer to Add (ml):2885.35
