Description

Amount:  100 µL

Background:  Lipid droplets are coated with a layer of proteins that regulate their growth and metabolism.  The major lipid droplet-associated protein in adipocytes is perilipin [1]. Mice in which the endogenous gene for perilipin is knocked out have a lean phenotype due to reduced accumulation of fat [2,3], suggesting that perilipin may have a “gate-keeper” function under basal conditions to protect the triglycerides from metabolism by lipases.

Immunogen:  Synthetic peptide corresponding to the region surrounding serine 497 of the human perilipin 1 sequence (not specific to serine 497 phosphorylation)

Specificity/Target:  Recognizes full-length perilipin 1 (encoded by the PLIN1a gene)

Species Reactivity:  human, mouse (verified)

Tested Applications:  Immunocytochemistry/immunofluorescence (ICC/IF), Western blotting (WB)

Recommended Dilutions    ICC/IF    1:300        |      WB       1:5000

Storage:  4°C short-term; -20°C long-term

Available volume discounts and contract testing services.


Human subcutaneous adipocytes stained for nuclei (blue), lipid droplets (green), and perilipin (red) using Vala Sciences’ lipid droplet staining kit (#4805) and mouse monoclonal antibody to perilipin (# 4854).

Western blotting of protein extracts from 3T3L1 cells that were differentiated into adipocytes and treated with and without 6 µM forskolin. The antibody to perilipin (#4854) recognizes a distinct band at approximately 57 kD.
