Medchemexpress LLC Desthiobiotin polyethyleneoxide iodoacetamide | MFCD06202009 | 97.7% | 583.46 | C21H38IN5O6 | 5 MG
Desthiobiotin polyethyleneoxide iodoacetamide is an iodoacetamide-based probe that labels cysteine residues by alkylation, introducing a desthiobiotin affinity tag through a polyethylene oxide linker for enrichment and downstream mass spectrometry-based chemoproteomic analysis.
- Selectively alkylates cysteine thiols for targeted labeling.
- Introduces a desthiobiotin affinity handle for streptavidin-based enrichment.
- Polyethylene oxide linker improves solubility and reduces steric hindrance.
- Compatible with chemoproteomic workflows and mass spectrometry analysis.
- Stable as a powder when stored at -20°C for extended periods.
Cayman Chemical Sulfo-NHS-BIotIn 50mg
An amine-reactive biotinylation reagent; commonly used in the biotin labeling of amine-containing proteins, antibodies, and other molecules
Biotium Giardia lamblia(BB1.1E5), CF568 conjugate, 0.1mg/mL
Giardiasisis a diarrheal illness caused by a single celled microscopic protozoan parasite, Giardia lamblia, also known as Giardia intestinalis. Giardia lamblia exists in two forms, an active form called a trophozoite, and an inactive form called a cyst. The active trophozoite attaches to the lining of the small intestine and is responsible for causing the signs and symptoms of giardiasis. The trophozoite cannot live long outside of the body and spread of infection is via the cyst, which is excreted in the host's feces. When it is ingested, stomach acid activates the cyst, and the cyst develops into the disease causing trophozoite in the new host. Giardiasis is diagnosed by finding cysts or trophozoites in the feces. Primary antibodies are available purified, or with a selection of fluorescent CF Dyes and other labels. CF Dyes offer exceptional brightness and photostability. Note: Conjugates of blue fluorescent dyes like CF405S and CF405M are not recommended for detecting
Cayman Chemical Cortexolon 17a-propIonate 5mg
A peripherally selective androgen receptor antagonist; binds to AR and inhibits AR-regulated transcription in a reporter cell line in vitro; inhibits androgen-regulated lipid synthesis in primary human sebocytes; inhibits inflammatory cytokine production from primary human sebocytes and scalp dermal papilla cells; inhibits testosterone propionate-induced flank organ enlargement in Syrian golden hamsters by 84% when administered topically at 400 μg/animal

Enzo Life Sciences Fluorescein-5-maleimide (ultra pure) (25mg). CAS: 75350-46-8
Fluorescein-5-maleimide enables protein labeling via thiol modifications in most proteins at cysteine residues that either are intrinsically present or resulted from reduction of cystine residues. Unlike iodoacetamides, maleimides do not react with histidine and methionine under physiological conditions. The probe is suitable for assessing conformation- dependent accessibility of cysteine residues in proteins. Wavelength Maxima: Excitation 493nm, Emission 515nm Purity: ≥95% (HPLC). Solubility: Soluble in DMSO. Long Term Storage: -20°C.
