Lumiprobe Sulfo-Cyanine7 azide, 1 mg
A water-soluble NIR dye azide for Click Chemistry. Sulfo-Cyanine7 is a cyanine dye, an analog of Cy7 with improved photophysical properties. This dye is a perfect choice for NIR imaging studies in live organisms.
Biotium CD11c(HC1/1), CF568 conjugate, 0.1mg/mL
CD11c, also known as Integrin, alpha X (complement component 3 receptor 4 subunit) (ITGAX), is a type I transmembrane protein found at high levels on most human dendritic cells, but also on monocytes, macrophages, neutrophils, and some B cells. It induces cellular activation and helps trigger neutrophil respiratory burst. It is expressed in hairy cell leukemias, acute non-lymphocytic leukemias, and some B-cell chronic lymphocytic leukemias.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 low abundance targets, because blue dyes have lower fluorescence and can give higher non-specific background than other dye colors.
Biotium CD66 (CEA)(C66/195), 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 reacts with nonspecific cross-reacting antigen (NCA) and shows a cross-reaction 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 ) from pleural mesotheliomas (rarely or weakly CEA ). 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 Dy
Aat Bioquest 7-Hydroxy-4-methylcoumarin [4-Methylumbelliferone] *Fluorescence reference standard*
This compound is used as a calibration standard for 7-hydroxy-4-methylcoumarin-based enzyme substrates. It has pH-dependent fluorescence.
Proteintech Group Inc Histone-Label Atto488
Histone-Label* is a fluorescent chromatin probe for direct staining of chromosomes and nuclei. It consists of an anti-histone VHH conjugated to the fluorescent dye ATTO488. For IF, microscopy of histones, chromosomes, and nuclei.
Aat Bioquest 5-TAMRA, SE [5-Carboxytetramethylrhodamine, succinimidyl ester] *CAS#: 150810-68-7*
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.
Aat Bioquest Cyanine 5 azide [equivalent to Cy5® azide]
A variety of cyanine 5 ( Cy5®) dyes has been used to label biological molecules for fluorescence imaging and other fluorescence-based biochemical analysis. They are widely used for labeling peptides, proteins and oligos etc.
Aat Bioquest Texas Red® cadaverine *Single Isomer*
Texas Red® cadaverine reacts with carbonyl compounds such as aldehyde, ketones and acids to give bright red fluorescent conjugates. It is widely used for labeling glycoproteins and carbohydrates through reductive amination.
