Background Information

SREBF2,also named as BHLHD2, is a 1141 amino acid protein, which contains 1 bHLH domain and belongs to the SREBP family. SREBF2 localizes in the endoplasmic reticulum membrane and is ubiquitously expressed in adult and fetal tissues. SREBF2 as a transcriptional activator is required for lipid homeostasis. SREBF2 expression is dynamically regulated in response to nutritional and hormonal cues. SREBF2 exists two isoform with molecular weight 124 kDa and 73 kDa.

Bertrand (Verified Customer) (04-08-2024)

This is a Srebp2 antibody, however, the results from western blot analysis show that the product might not be specific to Srebf2...There are lots of non-specific bands and the uncleaved/immature protein should not be present in the nucleus of cells, yet it was there.

  • Applications: Western Blot
  • Primary Antibody Dilution: 1:1000
  • Cell Tissue Type: Liver homogenates

Boyan (Verified Customer) (04-17-2023)

OK for WB, a specific but weak band was seen around 150 kd, but not 130 kd, which is shown on its booklet. The 130 kd band is a strong nonspecific band.

  • Applications: Western Blot
