General Notes
This product (Catalog No. CABT-BL5199) is a rabbit-derived polyclonal antibody raised against human MRPS33. This antibody exhibits cross-reactivity with MRPS33 from mouse. It has been affinity purified by Protein A. Mammalian mitochondrial ribosomal proteins are encoded by nuclear genes and help in protein synthesis within the mitochondrion. Mitochondrial ribosomes (mitoribosomes) consist of a small 28S subunit and a large 39S subunit. They have an estimated 75% protein to rRNA composition compared to prokaryotic ribosomes, where this ratio is reversed. Another difference between mammalian mitoribosomes and prokaryotic ribosomes is that the latter contain a 5S rRNA. Among different species, the proteins comprising the mitoribosome differ greatly in sequence, and sometimes in biochemical properties, which prevents easy recognition by sequence homology. The 28S subunit of the mammalian mitoribosome may play a crucial and characteristic role in translation initiation. This gene encodes a 28S subunit protein that is one of the more highly conserved mitochondrial ribosomal proteins among mammals, Drosophila and C. elegans. Splice variants that differ in the 5' UTR have been found for this gene; all variants encode the same protein. Pseudogenes corresponding to this gene are found on chromosomes 1q, 4p, 4q, and 20q.
CABT-BL5199 is suitable for use in Western blot (WB) (1:500–1:1,000) application.
CABT-BL5199 is supplied as a liquid formulation in 0.42% Potassium phosphate, 0.87% Sodium chloride, pH 7.3, 30% glycerol, and 0.01% sodium azide. For long-term storage, keep at −20 °C. For short-term use, store at 2–8 °C. Avoid repeated freeze–thaw cycles to maintain antibody integrity and performance.
