AURORA BIOLABS LLC PreScission Protease (HRV 3C), 1000 units
PreScission Protease is a fusion protein of glutathione S-transferase (GST) and human rhinovirus (HRV) type 14 3C protease. The protease specifically recognizes a subset of sequences which include the core amino acid sequence Leu-Phe-Gln/Gly-Pro cleaving between the Gln and Gly residues. Substrate recognition and cleavage are likely to be dependent not only upon primary structural signals, but also upon the secondary and tertiary structures of the fusion protein as well.

Dojindo Molecular Technologies Inc -SulfoBiotics- PEG-PCMal (1 mg): monitor redox state of proteins in biological samples, visualize modification of thiol residues by electrophoresis, high transfer efficiency in Western Blotting.
PEG-PCMal is a reagent used to visualize the redox states of protein by electrophoretic analysis. PEG-PCMal has a maleimide group that binds a protein thiol group. A mobility shift corresponding to about 5 kDa is observed by electrophoretic analysis for each molecule of PEG-PCMal binds to a free thiol group of the target protein. The conventional reagent, PEG-Maleimide is widely used in mobility shift assays, however, transfer efficiency and antibody recognition on Western blot are low, due to the PEG chains on the labeled protein.PEG-PCMal has a UV-photocleavable moiety in the molecule. The PEG chains are cut off from the labeled protein in the gel with UV irradiation after electrophoresis. Therefore, the protein treated with UV irradiation can be transferred from the gel to a PVDF membrane and detected by Western blot. Dojindo offers various sulfur biology reagents.

Gene Tools LLC Endo-Porter PEG, Safe Cytosolic Delivery, Low Toxicity, 1 mL
Endo-Porter PEG is an innovative amphiphilic peptide reagent designed for safe and efficient cytosolic delivery of macromolecules into cultured cells. Its unique endocytosis-mediated mechanism ensures effective cargo escape from endosomes while minimizing toxicity. Unlike other methods, it requires no cargo pre-incubation and works optimally even in 10% serum. This simplifies protocols and offers reduced toxicity, making it a go-to choice for researchers in cellular delivery applications.

Aat Bioquest XFD532 PEG4 biotin conjugate, 1mg
The XFD532 PEG4 biotin conjugate incorporates the XFD532 fluorophore, which is structurally identical to Alexa Fluor 532 and efficiently excited at 532 nm. It exhibits strong orange fluorescence and high avidin-binding efficiency, closely resembling native biotin in affinity, rapid association, and non-cooperative binding to avidin and streptavidin tetramers. This conjugate is particularly well suited for the detection and quantification of biotin-binding sites on avidin, streptavidin, or neutravidin. In contrast to Biotin-4-fluorescein, which suffers from poor aqueous solubility, pH-dependent absorbance, and short-wavelength emission, the XFD532 PEG4 biotin conjugate is fully water soluble and maintains pH-independent fluorescence across the range of pH 4–10.
