Cluster of differentiation 57 (CD57), also known as NK-1, is an antigen detectable in natural killer cells, some T-lymphocytes and normal peripheral blood mononuclear cells, myeloid cells, and a variety of polypeptides, lipids, and chondroitin sulfate proteoglycans. CD57 is indicated as a marker for tumors of neuroendocrine origin, including pheochromocytomas, paragangliomas, carcinoid tumor, and medulloblastomas, as well as various neural tumors including neuromas, neurofibromas, schwannomas, and granular cell tumors. CD57 is also detectable in ganglioneuroma and prostate carcinoma. Anti-CD57 is used to distinguish nodular lymphocyte-predominant Hodgkin’s lymphoma from T-cell/histiocyte-rich large B-cell lymphoma, nodular sclerosis Hodgkin’s disease, and follicular lymphoma.
Introduction
The Kit integrates phenol/guanidine-based lysis and silica membrane purification of total RNA. MagZol Reagent, included in the kits, is a monophasic solution of phenol and guanidine thiocyanate, designed to facilitate lysis of samples and inhibit RNases. The high lysis efficiency of the reagent and the subsequent removal of contaminants by organic phase extraction enable extracting up to 200μg total purified RNA from less than 100mg animal, plant, fungal samples,bacteria, cells and other samples.

Tissue samples (10-100mg) are homogenized in MagZol Reagent. After addition of chloroform, the homogenate is separated into aqueous and organic phases by centrifugation. The upper, aqueous phase is extracted, and ethanol is added to provide appropriate binding conditions. The sample is then applied to the spin column, where the total RNA (up to 100µg) binds to the membrane and phenol and other contaminants are efficiently washed away. High-quality RNA is then eluted in 30-100µl of RNase-free water.

Storage and Stability
MagZol Reagent should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect its performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions.

Description
The FluoroStain™ Protein Fluorescent Staining Dye (Red, 1000×) is designed to substitute the common Coomassie Blue protein staining method, offering greater sensitivity and ease of operation. Unlike Coomassie Blue stain, the FluoroStain Protein Fluorescent Staining Dye binds to protein with high specificity, making destaining process an option rather than a requirement. With further reduction of background signals via destaining process, the FluoroStain™ is capable of achieving detection level parallel to silver staining without specialized imaging equipment, making it one of the most sensitive dyes available. In addition to its remarkable sensitivity, the FluoroStain™ Protein Fluorescent Staining Dye (Red, 1000×) brings a more reliable and safer user experience, since the stained gel can be visualized with blue-light illumination, avoiding the risk of skin/ eye damage caused by UV light. For best result, we suggest using B-BOX™ Blue Light LED epi-illuminator to visualize and analyze the gel stained with FluoroStain Protein Fluorescent Staining Dye (Red, 1000×). The FluoroStain™ Protein Fluorescent Staining Dye is compatible to the analysis of mass spectra, i.e. LC-MS/MS, MALDI-TOF, etc.
Spectral Characteristics
When it is bound with bovine serum albumin (BSA), the fluorescent emission of FluoroStain Protein Fluorescent Staining Dye can be excited by UV and blue light sources, with excitation peaks around 369 and 517 nm and emission at 605 nm. In absence of BSA, FluoroStain Protein Fluorescent Staining Dye shows ignorable fluorescence as compared with protein-bound form, therefore giving a clear background for photographic analysis.
These spectral characteristics made this fluorescent dye compatible with a wide variety of gel reading facilities, including UV/ blue light epi- and transilluminator, argon laser and mercury-arc lamp excitation gel scanners.
Storage
Protected from light
-20°C for 24 months
