1. Organoid culture
1. ORGANOID CULTURE
Organoid culture is a 3-dimentional culture method that enables the recapitulation of the tumor microenvironment and the success rate reported is higher than the 2-dimentional culture.
Organoid Culture Product Highlight
Afamin/Wnt3a CM serum free conditioned medium including Wnt3a-Afamin complex for intestinal organoid cell culture.
Autophagy is a cellular self-digestion process for the purpose of providing nutrients to allow for cell survival during stress conditions. Autophagy can be selective (mitophagy) or non-selective (nutrient poor). Autophagy plays an important role in maintaining the cell homeostasis by removing non-essential cell components. The role of autophagy is generally understood to be securing nutrient sources through autodigestion to survive starvation conditions. However, in recent years, it has been found to work along with the proteasome system in the metabolism of cell components even in normal environments. Compared to proteasomes, which selectively degrade ubiquitinated proteins as their targets, in autophagy the space within the cell is entirely digested; therefore, it is called a bulk degradation system. Recent research and advances have shown an association of mammalian autophagy with diseases such as neurodegenerative disease, infection disease, cardiac disease as well as cancers.
Autophagy Product Highlights
1. PM045: Anti-p62 (SQSTM1) (Human) pAb (Polyclonal Antibody)
2. PM036: Anti-LC3 pAb (Polyclonal Antibody)
3. CY-7055: Total p62 ELISA Kit
p62/SQSTM1 interacts with various molecular groups such as RIP, TRAF6, ERK, aPKCs, and poly-ubiquitin through PB1 domain, Zn finger domain, and UBA domain. This protein directly interacts with LC3, which is localized on autophagosome membrane, and is degraded by autophagic-lysosome pathway. p62 regulates ubiquitin-positive protein aggregates caused by autophagy deficiency.
PM045: Anti-p62 (SQSTM1) (Human) pAb (Polyclonal Antibody)
This antibody was purified from rabbit serum using affinity column. The rabbit was immunized with the recombinant human p62 protein corresponding to amino acids (120-440).
PM036: Anti-LC3 pAb (Polyclonal Antibody)
This antibody was purified from rabbit serum using protein A agarose. The rabbit was immunized with the recombinant human LC3 [MAP1LC3B (1-120 aa).
CY-7055 CycLex® Total p62 ELISA Kit
Total p62 ELISA Kit is used for the quantitative measurement of human or mouse p62 protein in cell lysate.
Mitophagy is the selective degradation of old or depolarized mitochondria by autophagy and contributes to maintaining a healthy population of mitochondria. Since damaged mitochondria lead to collapse cell homoeostasis, mitophagy is believed to be protective against diseases related to mitochondrial dysfunction such as in neurodegenerative disorders.
Mitophagy Product Highlight:
AM-V0259M: pMitophagy Keima-Red mPark2 (Kan)
Mitophagy detection vectors are designed for the co-expression of MT-mKeima-Red. (CoralHue®Mitochondria-targeted monomeric Keima-Red) gene and mouse Parkin (mPark2) gene from the internal ribosome entry site (IRES), as part of a bicistronic transcript in mammalian cells. Keima-Red has been cloned from Montipara sp. A monomeric version of CoralHue®Keima-Red (mKeima-Red) displays a bimodal excitation spectrum with peaks at 440 and 586nm in neutral and acidic solutions, respectively, and an emission maximum at 620nm. Mitochondrial targeting of mKeima-Red is achieved by introducing a mitochondrial signal sequence at the N-terminus of mKeima-Red.
Apoptosis, a form of programmed cell death, is not only a major process within normal homeostasis but is present in disease states such as cancer and many autoimmune and neurodegenerative diseases. Apoptosis is accompanied by condensation of cytoplasm, loss of plasma membrane microvilli, condensation and fragmentation of nuclei, and extensive degradation of chromosomal DNA into oligomers of about 180 bp. A large number of molecules are involved in carrying out and regulating apoptosis.
Apoptosis Product Highlight:
4700 MEBCYTO® Apoptosis Kit (Annexin V-FITC Kit)
The MEBCYTO® Apoptosis Kit (Annexin V-FITC Kit) (4700) can identify cells in an earlier stage of apoptosis.
The epigenetics field continues to gain significance as we discover there are more causes to DNA mutations outside of hereditary contribution. Gene expression that is turned on/ off due to external factors, such as environment or diet, continue to draw researchers to discover exactly how these genes become altered.
RIP-Assay Kit is optimized for performing the RIP-Chip process. In the RIP-Assay protocol, mRNP complexes are isolated from cell extracts by immunoprecipitation with RIP-Certified Anti-RBP Antibodies provided from MBL. mRNAs are isolated from mRNPs using guanidine hydrochloride. Thus, RIP-Assay Kit does not contain phenol or chloroform, allowing safe isolation of “high-quality RNA” from RNP complexes without degradation. Once purified, the RNAs present in the complex are analyzed to identify the target mRNAs using various molecular biology tools such as RT-PCR, gene expression analysis based on microarray technology (Chip analysis), or sequencing.
