描述

Enterotoxin type G Proteinas, a staphylococcal enterotoxin, is implicated in staphylococcal food poisoning syndrome, causing severe symptoms like high fever, hypotension, diarrhea, shock, and fatalities. Its ability to induce a range of adverse effects underscores its significance in foodborne illnesses, emphasizing the severity of impact on affected individuals. Enterotoxin type G Protein, S. aureus (His-SUMO) is the recombinant Staphylococcus aureus-derived Enterotoxin type G protein, expressed by E. coli , with N-His, N-SUMO labeled tag. The total length of Enterotoxin type G Protein, S. aureus (His-SUMO) is 233 a.a., with molecular weight of ~43.0 kDa.
研究背景

G 型肠毒素是葡萄球菌肠毒素的一员，与葡萄球菌食物中毒综合征的发生有关。这种综合征的特点是严重症状，包括高烧、低血压、腹泻、休克，在某些情况下甚至导致死亡。肠毒素引起如此一系列不利影响的能力强调了其在食源性疾病中的重要性，并强调了其对受影响个体影响的严重性。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)
× = ×
C1   V1   C2   V2

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
