In Table I, the specific activity data for both wild type and perilipin-null (3rd row, 2nd and 3rd columns) should read “25” units, not “25%” as published in the original article. The corrected table appears below.
Table I.
Adipose tissue of perilipin -null animal contains HSL of normal specific activity
| Animal | Wild type | perilipin-null |
|---|---|---|
| Densitometry (arbitrary units) |
16,900 | 13,000 |
| Activity (nmol/h × mg protein−1) |
686 | 518 |
| Specific activity | 25 | 25 |
Aliquots of infranatants from adipose tissue of wt and perilipin-null mice were tested for lipolytic activity as described under Materials and methods. Equivalent cellular aliquots were electrophoresed under SDS-PAGE, immunoblotted with affinity-purified anti-HSL, and scanned with a densitometer. The values for densitometric scans were divided by the activity values to give specific activities, revealing that the samples from both types of animals had identical specific activities.
