Active Motif Sortag-IT™ 3X DBCO Click Labeling Kit, 3 x 100 µg
Sortag-IT™ Labeling Kits are designed for site-specific labeling of Active Motif's highly specific AbFlex® recombinant antibodies (rAb) via the Sortase tag recognition sequence (LPXTG) that is incorporated into the heavy chains of each AbFlex antibody. Directly conjugate fluorophores, enzymes (HRP, AP), biotin, peptides, DNA, carbohydrates, or other labels to the terminal end of the heavy chain to ensure the antigen binding site remains available for target recognition.
Medchemexpress LLC N-DBCO-N-bis(PEG2-C2-acid) | 2110449-00-6 | 96.7% | C33H40N2O10 | 100 MG
N-DBCO-N-bis(PEG2-C2-acid) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs. It is a click chemistry reagent, containing a DBCO group that can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing Azide groups.
- PEG-based PROTAC linker
- Can be used in the synthesis of PROTACs
- Click chemistry reagent
- Contains a DBCO group for strain-promoted alkyne-azide cycloaddition (SPAAC) with Azide groups
Medchemexpress LLC DSPE-PEG-Folate | 1236288-25-7 | MFCD07107414 | 95.7% | 5000 | 5 MG
DSPE-PEG-Folate (MW 5000) is a PEGylated phospholipid in which DSPE is linked to a polyethylene glycol chain terminated with folic acid. It is designed to incorporate into liposomes or nanoparticle surfaces to present folate ligands for receptor-mediated targeting and uptake, and is used in targeted drug delivery, imaging, and nanoparticle functionalization in research settings.
- Facilitates folate-receptor mediated targeting.
- Integrates into lipid bilayers and can form micelles.
- Average molecular weight of 5000 for extended circulation properties.
- High purity (≈95.7%) suitable for research applications.
- Stable as a powder when stored at -20°C for long-term storage.
Cayman Chemical Boc-NH-PEG3-OH 500mg
A PEGylated building block; has been used as a spacer in biotinylated heterobifunctional cross-linker agents; has been used as a spacer in near infrared imaging probes for CYP1B1, which is expressed in a variety of tumors; has also been used in the synthesis of graftable peptidomimetics that bind to human αVβ3 integrin and inhibit adhesion of human osteoprogenitor cells to vitronectin
Sigma Aldrich Fine Chemicals Biosciences Collagenase H from Clostri
Collagenase H is an enzyme mixture prepared from Clostridium histolyticum cultures by filtration ammonium sulfate precipitation dialysis and lyophilization.
Sigma Aldrich Fine Chemicals Biosciences LpodsqR StyreneMalec A100MG
Lipodisq(R) polymers contain styrene and maleic acid monomer units. This product is the pre-hydrolyzed form of the SMA polymer with the styrene and maleic acid monomers. These polymer-lipid complexes are mainly generated by detergent-free methods.
Medchemexpress LLC DSPE-Thiol | 144735-82-0 | MFCD29079392 | 90.0% | 836.19 g·mol⁻¹ | C44H86NO9PS | 5 MG
A thiol-capped distearoyl phosphatidylethanolamine (DSPE) phospholipid for thiol-based conjugation and lipid surface modification. The terminal thiol selectively reacts with maleimide and other thiol-reactive groups, enabling preparation of phospholipid dimers, surface functionalization of liposomes or lipid nanoparticles, and formation of stable thiol-linked conjugates. Supplied as a solid with reported solubility information for DMF and typical purity at 90.0%.
- Thiol-functionalized head group for selective thiol-maleimide conjugation.
- Suitable for liposome surface modification and nanoparticle functionalization.
- Enables preparation of phospholipid dimers and thiol-linked conjugates.
- Soluble in DMF with sonication and gentle heating to aid dissolution.
- Typical purity 90.0% and molecular weight 836.19 g·mol⁻¹.
