Protein Labeling Reagents
Biotium CD63 (Late Endosomes Marker)(LAMP3/2881), Biotin conjugate, 0.1mg/mL
This MAb recognizes protein of 26 kDa-60 kDa, which is identified as CD63. The tetraspanins are integral membrane proteins expressed on cell surface and granular membranes of hematopoietic cells and are components of multi-molecular complexes with specific integrins. The tetraspanin CD63 is a lysosomal membrane glycoprotein that translocates to the plasma membrane after platelet activation. CD63 is expressed on activated platelets, monocytes and macrophages, and is weakly expressed on granulocytes, T cell and B cells. It is located on the basophilic granule membranes and on the plasma membranes of lymphocytes and granulocytes. CD63 is a member of the TM4 superfamily of leukocyte glycoproteins that includes CD9, CD37 and CD53, which contain four transmembrane regions. CD63 may play a role in phagocytic and intracellular lysosome-phagosome fusion events. CD63 deficiency is associated with Hermansky-Pudlak syndrome and is strongly expressed during the early stages of melanoma pr
Bioworld Protein-A Gold™ (5-10 nm), 1 mL
Protein-A Gold Protein-A is a highly stable cell surface receptor produced by several strains of Staphylococcus aureus. It is capable of binding to the Fc portion of immunoglobulins, especially IgG from a large number of species. Protein-A may be conjugated with various reporter molecules, including colloidial gold, without affecting the antibody binding site on the molecule. Specifications:Particle size5-10 nm (monodisperse), nominal 15 nm (colloidal gold) Suspension in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin, 20% glycerol, and 15 mM sodium azide. Storage: 2-8 C
Biotium CD63 (Late Endosomes Marker)(LAMP3/2788), Biotin conjugate, 0.1mg/mL
This MAb recognizes protein of 26 kDa-60 kDa, which is identified as CD63. Its epitope is different from that of MAb LAMP3/529. The tetraspanins are integral membrane proteins expressed on cell surface and granular membranes of hematopoietic cells and are components of multi-molecular complexes with specific integrins. The tetraspanin CD63 is a lysosomal membrane glycoprotein that translocates to the plasma membrane after platelet activation. CD63 is expressed on activated platelets, monocytes and macrophages, and is weakly expressed on granulocytes, T cell and B cells. It is located on the basophilic granule membranes and on the plasma membranes of lymphocytes and granulocytes.

Medchemexpress LLC CalFluor 488 Azide | 1798305-98-2 | C37H49N5O13S2 | 1 MG
CalFluor 488 Azide is a water-soluble fluorogenic azide probe that is activated by Cu-catalyzed or metal-free click reactions. It remains non-fluorescent until it reacts with alkynes, making it ideal for specific applications. The azide group allows for copper-catalyzed azide-alkyne cycloaddition (CuAAc) with alkyne-containing molecules or ring strain-promoted alkyne-azide cycloaddition (SPAAC) with DBCO or BCN groups.
- Water-soluble fluorogenic azide probe
- Activated by Cu-catalyzed or metal-free click reactions
- Non-fluorescent until reaction with alkynes
- Capable of copper-catalyzed azide-alkyne cycloaddition (CuAAc)
- Capable of ring strain-promoted alkyne-azide cycloaddition (SPAAC)
- Used for biological conjugation and label coupling
- Categorized as a fluorescent dye and azide reactive dye for click chemistry
Apexbio Technology LLC D-Desthiobiotin 533-48-2 500mg
D-Desthiobiotin (CAS 533-48-2) is a derivative of biotin lacking the thiophene ring It binds to avidin and streptavidin with lower affinity compared to biotin enabling reversible interaction in affinity purification and protein chromatography protocols This property facilitates gentle elution of biotinylated proteins or other biomolecules without harsh conditions D-Desthiobiotin is widely employed for the labeling detection and isolation of proteins and cells in biochemical and cell-based assays providing an efficient tool for applications requiring temporary and specific capture of biomolecular targets
Cayman Chemical MyrIstIc ACD methyl STRd2 50mg
An internal standard for the quantification of myristic acid methyl ester by GC- or LC-MS
Enzo Life Sciences AMPIGENE qPCR 1-Step Probe Kit Lo-ROX (200Reactions)
AMPIGENE qPCR 1-Step Probe Kits use the latest developments in reverse transcriptase (RTase) technology and buffer chemistry for efficient cDNA synthesis and qPCR in a single tube. The modified MMLV RTase is blended with RNase inhibitor to prevent degradation of RNA by contaminating RNase. The RTase is thermostable and extremely active. AMPIGENE qPCR 1-Step Probe Kits are designed for use on a variety of probes including: Taqman, Molecular Beacons, and Scorpion probes. An optimized buffer system allows efficient amplification and proprietary enhancers prevent the formation of primers/dimers to increase sensitivity and specificity. ROX is a reference dye which is used to normalize fluorescent signal in qPCR. AMPIGENE qPCR 1-Step Probe Kits come with either Lo-ROX, Hi-ROX, or No-ROX concentration. Choose the appropriate ROX concentration for the instrument (see instrument compatibility for reference dye chart below.) Applications: PCR.
