SIAE Protein, Human (HEK293, His)

Cat. No.: HY-P71309
COA Handling Instructions

SIAE proteins play a key role in cellular processes by catalyzing the removal of the O-acetyl ester group specifically from the 9-position of the parent sialic acid N-acetylneuraminic acid. Through this enzymatic activity, SIAE helps regulate sialic acid modifications, affecting various biological functions associated with cell surface glycoconjugates. SIAE Protein, Human (HEK293, His) is the recombinant human-derived SIAE protein, expressed by HEK293 , with C-6*His labeled tag. The total length of SIAE Protein, Human (HEK293, His) is 500 a.a., with molecular weight of 64-77 kDa.

Background

The SIAE (Sialic Acid Acetylesterase) protein is an enzyme that plays a crucial role in sialic acid metabolism by catalyzing the removal of O-acetyl ester groups from position 9 of the parent sialic acid, N-acetylneuraminic acid. This enzymatic activity is important for regulating the structural modifications of sialic acids, which are essential components of glycoproteins and glycolipids. SIAE-mediated deacetylation at position 9 influences the overall charge and structure of sialic acids, impacting cellular interactions, immune responses, and signal transduction. Understanding the functions of SIAE provides insights into the dynamic regulation of sialic acid modifications and their implications for various physiological processes.

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.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

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

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