- Chrome azurol S (CAS) is a method that can be used to detect the mobilization of iron. In many soils iron is not often in an abundant form that plants can readily uptake and use.Siderophores are produced by rhizosphere bacteria to help enhance plant growth by increasing the availability of iron near the root (1).o perform CAS analysis a strong ligand (e.g. siderophore) is added to a highly colored iron dye complex. When the iron ligand complex is formed the release of the free dye is accompanied with a color change (7). Since CAS assay is high in sensitivity it is able to be used on agar plates.

CRISPR/Cas9 & Targeted Genome Editing: New Era in Molecular Biology The development of efficient and reliable ways to make precise, targeted changes to the genome of living cells is a long-standing goal for biomedical researchers. Recently, a new tool based on a bacterial CRISPR-associated protein-9 nuclease (Cas9) from Streptococcus pyogenes has generated considerable excitement (1).

Semi-quantitative Immunohistochemical Assay versus onco type DXÂ® qRT-PCR Assay for Estrogen and Progesterone Receptors Estrogen receptor (ER) status is a proven prognostic marker in breast cancer; however, its main clinical value is its ability to predict response to hormonal therapy. Most laboratories in the United States use immunohistochemistry to determine ER and progesterone receptor (PR) results on primary breast carcinomas.

Detection of siderophore production from several fungi and bacteria by a modification of chrome azurol S (CAS) agar plate assay However, the high toxicity of CAS-blue agar medium caused by the presence of a detergent impedes its utilization with many varieties of fungi and Gram-positive bacteria. To solve this problem, a modification of the CAS-agar plate assay was made by incorporating the CAS-blue dye in a medium with no contact with the microorganisms tested. Half of each plate used in our experiments was filled with the most appropriate culture medium for each type of microorganism and the other half with CAS-blue agar.

- The CRISPR/Cas system is a remarkably flexible tool for genome manipulation. One of the primary advantages of the technology is that the nuclease activity and the DNA-binding activity of Cas9 are discrete functions in the protein. The Cas9 nuclease activity (cut) is performed by 2 separate domains, RuvC and HNH.

What is CRISPR-Cas9? There is a lot of work focusing on eliminating ‘off-target’ effects, where the CRISPR-Cas9 system cuts at a different gene to the one that was intended to be edited. Better targeting of CRISPR-Cas9. In most cases the guide RNA consists of a specific sequence of 20 bases. These are complementary to the target sequence in the gene to be edited.

What is CRISPR/Cas9? Known as the “molecular scissor”, Cas9 is a nuclease that is responsible for the cutting of a sequence of DNA that has been identified by a CRISPR guide RNA. The “cutting”, which occurs through a biochemical interaction, allows the gene to be disabled, repaired or altogether replaced with a new strand of DNA.

What is the difference between a CAS graphing calculator and a non-CAS graphing calculator? A computer algebra system (commonly referred to as a CAS) is essentially software designed to manipulate mathematical expressions symbolically. Hence, a graphing calculator equipped with a CAS such as the TI-89 Titanium[1] or HP 50g[2] can perform mathematical functions on symbolic expressions and return symbolic expressions as results.

A Guide to Cheminformatics CAS Numbers are assigned by Chemical Abstracts Service (CAS), a division of the American Chemical Society. The CAS Registry, a database maintained by CAS, contains the authoritative list of all CAS Numbers and their chemical associations. As of May 23, 2013 the CAS Registry contained 71.6 million substances. The most recently-assigned CAS Number was 1432018‑50‑2. The last character of a CAS Number is a check digit derived mathematically from the preceding digits. Its purpose is to prevent human data-entry errors. Any change to the check digit or another digit has a high probability of producing an invalid CAS Number.

Coprecipitation From Wikipedia, the free encyclopedia. In chemistry, coprecipitation (CPT) or co-precipitation is the carrying down by a precipitate of substances normally soluble under the conditions employed. Analogously, in medicine, coprecipitation is specifically the precipitation of an unbound antigen along with an antigen-antibody complex. Coprecipitation is an important issue in chemical analysis, where it is often undesirable, but in some cases it can be exploited.
