Medchemexpress LLC Methoxy polyethylene glycol (mPEG) 13 carboxylic acid | 2170098-33-4 | MFCD28385486 | 95.0% | 632.74 g/mol | C28H56O15 | 1 G
m-PEG13-acid is a methoxy-terminated polyethylene glycol (PEG) linker bearing a terminal carboxylic acid. It is used as a flexible, hydrophilic spacer for bioconjugation and PEGylation; the carboxylic acid can be activated for amide formation with primary amines, making it suitable for linker construction in medicinal chemistry and PROTAC synthesis.
- Provides terminal carboxylic acid for facile amide coupling to primary amines
- Methoxy-terminated (monofunctional) PEG to limit crosslinking
- Flexible, hydrophilic spacer suitable for PEGylation and linker design
- Molecular weight ≈ 632.74 g/mol; formula C28H56O15
- Common applications include bioconjugation and PROTAC linker synthesis
- Supplied as a powder; follow supplier storage and handling guidance

Medchemexpress LLC Calreticulin/CALR M 50ug
Recombinant mouse calreticulin (GST-tagged) is a calcium-binding molecular chaperone supplied lyophilized for biochemical, binding, and assay development applications. The protein is expressed in E. coli and formulated for stability and low endotoxin to support sensitive downstream experiments.
- Expressed in E. coli for high-yield production.
- N-terminal GST tag for purification and detection.
- Purity greater than 95% by reducing SDS-PAGE.
- Low endotoxin level (<1 EU/μg) suitable for sensitive assays.
- Lyophilized from Tris-HCl with trehalose for enhanced stability.
- Store at -20°C; aliquot after reconstitution to avoid repeated freeze-thaw.
Medchemexpress LLC Bis(4-nitrophenyl) phosphate | 645-15-8 | 99.9% | 340.18 | 1 G
Bis(4-nitrophenyl) phosphate is a catalyst for metal micelles and can catalyze the hydrolysis of (4-nitrophenyl) phosphate. It is also an effective catalyst for ring-opening polymerization (ROP), which can achieve controlled polymerization of β-butyrolactone (β-BL) ring-opening and can be used to prepare diembedded polymers without quenching segment copolymer.
- For research use only.
Medchemexpress LLC p-Aminophenylmercuric acetate | 6283-24-5 | 99.1% | 351.75 | 1 G
p-Aminophenylmercuric acetate is an organomercurial activator of matrix metalloproteinases (MMP). It participates in the activation and inhibition of MMP-8 by attacking protein sulfhydryl or inducing cysteine switching reactions. It also promotes the shedding of betacellulin precursor (pro-BTC) and influences the binding of agonists and antagonists to the opiate receptor.
- Organomercurial activator of matrix metalloproteinases (MMP)
- Activates MMP-2 and MMP-9 at 0.5 mM for 30 minutes
- Decreases the apparent number of dihydromorphine binding sites and increases the sensitivity of agonist binding to the inhibitory effects of sodium in rat brain homogenate at 0-30 μM for 20 minutes
- Promotes the shedding of betacellulin precursor (pro-BTC)
- Influences the binding of agonists and antagonists to the opiate receptor
- Participates in the activation and inhibition of MMP-8
