Aat Bioquest 5-TAMRA SE [5-Carboxytetramethylrhodamine succinimidyl ester] CAS 150810-68-7 (100 mg)
The single TAMRA isomers are increasingly preferred for labeling peptides and nucleotides because they give better resolution in HPLC purification that is often required in the conjugation processes. This catalog is for 100 mg.

Biotium CD63 (Late Endosomes Marker)(LAMP3/2790), 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. 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 stro

Cayman Chemical Fluorescein 5 6-isothiocyana
An amine-reactive fluorescent probe; reacts with amine groups to form conjugates with proteins for detection by various fluorescent-based applications; ex/em = 485/535 nm, respectively
Dojindo Molecular Technologies Inc Fluorescein Labeling Kit-NH2 (3 samples) is used to prepare fluorescein-labeled proteins, high recovery in 1 hour, all processes in a single filtration tube, 50-200 µg/sample, Ex=500 nm, Em=525 nm.
Fluorescein Labeling Kit-NH2 is mainly used for the preparation of fluorescein-labeled proteins, such as IgG, for immunostaining and labeled cellular proteins for tracing. This kit contains all the reagents necessary for labeling. Amine-reactive fluorescein, a component of this kit, has succinimidyl groups (NHS) that react with the amino groups on proteins. Because this kit also includes a buffer exchange system, a sample containing amine base buffer can be labeled. Although membrane filtration sometimes causes IgG aggregation, the buffer system in this kit prevents aggregation during the concentration of IgG or fluorescein-labeled IgG solution. The excitation and emission wavelengths of the fluorescein-labeled IgG are 500 nm and 525 nm. The molecular weight of the protein to be labeled with this kit should be greater than 50,000. The amount of the protein is 50 ug-200 ug per sample. Dojindo offers various protein labeling reagents. (https://www.dojindo.com/labeling-chemistry/)
