Medchemexpress LLC Bromoacetamido-PEG4-NHS ester | 1260139-70-5 | 98.7% | C17H27BrN2O9 | 50 MG
Bromoacetamido-PEG4-NHS ester is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs. PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
- PEG-based PROTAC linker
- Used in the synthesis of PROTACs
- Enables selective degradation of target proteins
- Utilizes the intracellular ubiquitin-proteasome system

DSPE-PEG-FITC (MW 1000) is a fluorescein-labeled PEGylated phospholipid supplied as a powder. It functions as a fluorescent amphiphile that incorporates into lipid bilayers or forms micelles for labeling liposomes, nanoparticles, and membranes in fluorescence microscopy, flow cytometry, and tracking applications. Manufacturer documentation provides purity, storage, and handling details.
Medchemexpress LLC 1,2-Distearoyl-sn-Glycero-3-Phosphoethanolamine-N-azide | 2839508-98-2 | 96.4% | 831.11 g/mol | C43H83N4O9P | 5 MG
DSPE-N3 is an azide-functionalized distearoyl phosphoethanolamine used as a click-chemistry lipid for bioconjugation and nanoparticle formulation. The amphiphilic molecule presents an azide headgroup that enables copper-catalyzed azide-alkyne cycloaddition (CuAAC) to attach alkyne-containing probes, polymers, or targeting ligands, and is commonly applied in liposome and micelle formation, surface functionalization, and targeted delivery research.
- Contains an azide functional group for bioorthogonal click chemistry
- Amphiphilic structure supports liposome and micelle formation
- Suitable for conjugation of alkyne-bearing molecules via CuAAC
- High chemical purity for research-grade applications
- Store sealed at 4°C and protect from moisture for stability
- Available in small lab-scale quantities for formulation work

Worthington Biochemical Corporation COLLAGENASE TYPE 4 50 MG
Collagenase, Type 4 (Code: CLS-4), which is filtered through a 0.22 micron membrane and lyophilized in vials.
Sigma Aldrich Fine Chemicals Biosciences Collagenase B from Clostri
Collagenase B is prepared from Clostridium histolyticum cultures by filtration ammonium sulfate precipitation dialysis and lyophilization. Collagenase from Clostridium histolyticum is a collagenolytic enzyme. It interacts with collagen-like substances and is responsible for the degradation of collagen into small peptides. It is widely used for the disaggregation of many types of tissues (e.g. lung heart muscle bone adipose tissue liver kidney cartilage mammary gland placentae blood vessels brain tumors) and for the preparation of single-cell suspensions for the establishment of primary cell culture systems. Collagenase B is recommended when yield and viability are important.
Nacalai USA Inc TURBOTEV (TEV PROTEASE) 1MG
TurboTEV doesn't require any special buffer and can be used in a buffer most suitable for the target protein, It is a 52kDa protein with both GST and His tags so it can be removed by either Ni-chelating or Glutathione resin.
Sigma Aldrich Fine Chemicals Biosciences Collagenase Type Cls 100MG
This product is identical to Biochrom GmbH part numbers C2-22 and C2-28. Enzyme blending from collagenase clostripain with tryptic and proteolytic activities from Clostridium histolyticum. This preparation shows a high clostripain activity with the tryptic activity close to type I. Suitable for liver bone thyroid heart and salivary gland tissue. Specific activity is 125 to 250 Mandl units per milligram of powdered substance.
Medchemexpress LLC Cholesterol-PEG-azide | 85.7% | 3400 (average) | 5 MG
Cholesterol-PEG-azide (average MW 3400) is an amphiphilic cholesterol-polyethylene glycol conjugate bearing a terminal azide functional group. It serves as a clickable lipid anchor for bioconjugation and can self-assemble into micelles for use in drug delivery research and nanoparticle surface modification. Supplied as a white to off-white solid for research use.
- Provides an azide functional group for click chemistry.
- Amphiphilic structure enables micelle formation and membrane anchoring.
- Average PEG spacer (MW ~3400) offers flexible linker length.
