Question 1

Monday 29-August-2011

Why is the WB image showing a 75kDa band when the expected band size should be 35kDa?

ANSWER:

 

Thank you for your enquiry.

The 75kDa band could be due to insufficient boiling of the sample, which resulted in the 75kDa dimer band. Since this image is confusing, I have removed it from the datasheet. Please rest assured that the product does detect the expected 35kDa band, as stated in the following publication.

Kos K et al. Regulation of the fibrosis and angiogenesis promoter SPARC/osteonectin in human adipose tissue by weight change, leptin, insulin, and glucose. Diabetes 58:1780-8 (2009). WB; Human. PubMed: 19509023
