Phthalaldehyde  (Synonyms: Phthaldialdehyde)

製品番号: HY-W012669 純度: 99.80%
COA 取扱説明書 Technical Support

Phthalaldehyde (Phthaldialdehyde) reacts with proteins containing primary amines and blocked amino-terminal peptides of amino acids. Phthalaldehyde stabilizes bacterial outer membranes and cell walls, increases the optical density of bacterial cell suspensions, and inhibits bacterial lysis induced by ethylenediaminetetraacetic acid and sodium dodecyl sulfate. Phthalaldehyde exhibits bactericidal activity against Gram-negative vegetative bacteria.

製品説明

Phthalaldehyde (Phthaldialdehyde) reacts with proteins containing primary amines and blocked amino-terminal peptides of amino acids. Phthalaldehyde stabilizes bacterial outer membranes and cell walls, increases the optical density of bacterial cell suspensions, and inhibits bacterial lysis induced by ethylenediaminetetraacetic acid and sodium dodecyl sulfate. Phthalaldehyde exhibits bactericidal activity against Gram-negative vegetative bacteria[1][2].

体外実験

Phthalaldehyde (0.0025% (w/v); 1-180 min) reacts with lysine, glycine, and histidine to produce distinct UV absorption peaks at both acidic and alkaline pH, with reaction rates accelerating at higher pH; specific peak patterns and development times vary by amino acid[1].
Phthalaldehyde (0.05-0.2% (w/v); 2 h at 20 °C) induces dark color changes in pellets of Gram-negative (E. coli, P. aeruginosa) and Gram-positive (S. aureus) bacteria, with darker colors observed at alkaline pH and higher OPA concentration[1].
Phthalaldehyde (0.1% (w/v); 30 min at 20 °C) significantly inhibits EDTA-Tris induced lysis of Pseudomonas aeruginosa PA01[1].
Phthalaldehyde (0.1% (w/v); 30 min at 20 °C) significantly inhibits lysostaphin-induced lysis of Staphylococcus aureus NCTC 6571, with efficacy comparable to glutaraldehyde[1].
Phthalaldehyde (0.25-0.5% (w/v); 60 min) significantly increases the absorbance of Escherichia coli ATCC 9481, Staphylococcus aureus NCTC 6571, and Pseudomonas aeruginosa PA01 suspensions, with a greater increase in E. coli absorbance observed at the 0.5% (w/v) concentration[1].
Phthalaldehyde detects the blocked amino-terminal tryptic peptide of rat liver acyl-CoA oxidase by forming a fluorescent Schiff base with the peptide's free α-amino group[2].

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.
