AS20 4404 Anti-2S3M | 2S seed storage protein 3 (2S3 Albumin)

Arabidopsis thaliana dry seed extract from wilde-type (1) and mutants that accumulate precursors of major storage proteins: mag5-1, mag2-1 and mag4-1 (2-4) were separated on 15-20 % SDS-PAGE and blotted to PVDF membrane in wet system. Blot was blocked with 3 % skim milk/TBS-T, 1h/RT with agitation. Blot was incubated in the primary antibody at a dilution of 1: 2500 in TBS-T for 1h/RT. The antibody solution was decanted and the blot was washed 4 times for 10 min in TBS-T at RT with agitation. Blot was incubated in matching secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated) diluted to 1:10 000 in for 1h/RT with agitation. The blot was washed as above and developed with a chemiluminescent detection reagent, following manufacture's recommendations.
p2S - precursor of 2S; 2S-L - large subunit of 2S

2S seed storage protein 3, one of major seed storage proteins is synthesized on the endoplasmic reticulum as precursor and then transported to storage vacuoles, where it is processed by an asparaginyl endopeptidase to produce two mature polypeptides referred to as large and small subunits which are linked by disulfide bonds. Subcellular localisation: vacuole.

Alternative names:  2S albumin storage protein, NWMU2-2S albumin 3
