Aat Bioquest Fluorescein-5-maleimide *CAS 75350-46-8*
Maleimides are among the most frequently used reagents for thiol modification. In most proteins, the site of reaction is at cysteine residues that either are intrinsically present or resulted from reduction of cystines.

Aat Bioquest Tide Quencher™ 2WS maleimide [TQ2WS maleimide]
TQ2WS is designed to be a superior quencher to FAM, HEX, TET, JOE, TF2 and rhodamine 6G. TQ2WS has (a). much stronger absorption; (b). much higher quenching efficiency; and (c).
Biotium Phalloidin, CF594, 50 U
Phalloidin conjugates are actin filament stains for fixed and permeabilized cells. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Deep-red fluorescent CF594 has excitation/emission at 593/614 nm.
QA Bio Inc QA-Bio, Inc. • LudgerTag 2-AB Glycan Labeling Kits
2-AB Glycan Labeling Kits • 2-AB (2-aminobenzamide) is one of the most widely used fluorescent labels for glycosylation analysis. The LudgerTag 2-AB Labeling Kit includes all the reagents required to label up to 30 glycans samples.
Biotium CD66 (CEA)(COL-1), CF568 conjugate, 0.1mg/mL
This antibody recognizes proteins of 80-200 kDa, identified as different members of CEA family. CEA is synthesized during development in the fetal gut and is re-expressed in increased amounts in intestinal carcinomas and several other tumors. This MAb does not react with nonspecific cross-reacting antigen (NCA) and with human polymorphonuclear leucocytes. It shows no reaction with a variety of normal tissues and is suitable for staining of formalin/paraffin tissues. CEA is not found in benign glands, stroma, or malignant prostatic cells. Antibody to CEA is useful in detecting early foci of gastric carcinoma and in distinguishing pulmonary adenocarcinomas (60-70% are CEA positive) from pleural mesotheliomas (rarely or weakly CEA positive). Anti-CEA positivity is seen in adenocarcinomas from the lung, colon, stomach, esophagus, pancreas, gallbadder, urachus, salivary gland, ovary, and endocervix.Primary antibodies are available purified, or with a selection of fluorescent CF
Biotium ViaFluor 647, 50 uL
ViaFluor Live Cell Microtubule Stains are cell-permeable taxol probes for imaging the microtubule cytoskeleton in live cells. Available with blue, green, or far-red fluorescence.
