Company:

Atlas Antibodies

Product Name:

Anti-SULF1 antibody

Catalog Number:

HPA054728-100UL

Clone Number:

Polyclonal

Anti-Human SULF1 antibody tested against wild-type and SULF1-KO fibroblasts.KO was confirmed through PCR and sequencing, but antibody picked up bands in the KO cells, around the predicted molecular weight. This indicates the antibody is binding to something other than SULF1.

Experimental Design and Results Summary

Applications

Western Blot

Sample

HS27A bone marrow fibroblasts

Primary Incubation

1:1000, overnight 4*C in blocking buffer

Blocking Agent

TBS, 0.05% Tween-20, 5% non-fat dry milk, 1 hr RT

Secondary Incubation

Sheep anti-mouse HRP, 1:50000, 1hr, room temp

Tertiary Incubation

None

Detection

Enhanced Chemiluminescence

Results Summary

20 micrograms of HS27A cell lysate from wild-type and SULF1-KO cells were loaded in biological duplicates, each with technical duplicates.A band around 75 kDa was observed in all samples - curiously, this band is at the predicted molecular weight informed by the manufacturer, but it did not go away in cells that had SULF1-Knocked out.KO was confirmed through PCR and sequencing.

The Good

No pros

The Bad

Expensive, non-specific band detection

The Bottom Line

Researchers - do not use this antibody. It also did not perform well in ICC and IHC.
