Medchemexpress LLC Biotin-PEG4-alkyne | 1458576-00-5 | MFCD22380755 | 99.7% | C21H35N3O6S | 10MG
Biotin-PEG4-alkyne is a biotin-labeled polyethylene glycol linker bearing a terminal alkyne group for copper-catalyzed azide-alkyne cycloaddition (CuAAC). Supplied as a high-purity solid, it is intended for bioconjugation workflows, affinity capture and detection, and as a linker in targeted degradation (PROTAC) research.
- Terminal alkyne enables CuAAC click chemistry
- Biotin tag for affinity capture and detection
- PEG4 spacer improves solubility and reduces steric hindrance
- High purity for reproducible conjugation
- Available in small and bulk pack sizes for research needs
ABclonal Technology ANG Rabbit pAb
The protein encoded by this gene, known as RNase5 or angiogenin, is a member of the RNase A superfamily, though it has weak ribonucleolytic activity. It is a potent mediator of angiogenesis, binding to actin on endothelial cell surfaces to promote blood vessel formation. This protein also accumulates in the nucleolus to stimulate ribosomal transcription and, under stress, translocates to the cytosol to hydrolyze tRNAs, affecting protein synthesis. The mature protein, after cleavage of a signal peptide, contains a nuclear localization signal, a cell-binding motif, and a catalytic domain. It is neurotrophic, neuroprotective, and exhibits antimicrobial activity against bacteria and fungi, such as S. pneumoniae and C. albicans. This gene plays roles in cell growth and tumor progression, with mutations linked to amyotrophic lateral sclerosis (ALS). Alternative splicing produces multiple transcript variants encoding the same protein.

STEMCELL Technologies Collagenase C, ACF, Size: 100 mg
Collagenase C, Animal Component-Free (ACF) is obtained from cultures free of animal-derived materials. Collagenase is a protease consisting of a single polypeptide chain approximately 1,000 amino acid residues in length. Collagenase is capable of digesting native collagen fibrils commonly found in connective tissues and therefore is frequently used for tissue dissociation. Collagenase preparations contain the activity of several proteases including: collagenase, caseinase, clostripain, and trypsin (Kessler & Yaron). Collagenase C, ACF contains low levels of tryptic activity, similar to Collagenase Type IV, and is intended for use in applications where it is necessary to prevent the introduction of potential animal-derived pathogens.
