Target description

RNA-binding protein 39 (UniProt: Q14498; also known as CAPER alpha, CAPERalpha, Hepatocellular carcinoma protein 1, RNA-binding motif protein 39, RNA-binding region-containing protein 2, Splicing factor HCC1) is encoded by the RBM39 (also known as HCC1, RNPC2) gene (Gene ID: 9584) in human. RBM39 is an RNA-binding protein that acts as a pre-mRNA splicing factor. It is mainly involved in transcriptional regulation, alternative splicing, and protein translation. It is normally concentrated in nuclear speckles and has three RNA recognition motifs (RRM)(aa 153-230; 250-328; and 445-508). RBM39 is considered to be a key factor in tumor-targeted mRNA and protein expression and plays a vital role in tumorigenesis. It is expressed at high levels in human breast cancer tissues, but it was almost undetectable in normal breast tissues. Its levels are reported to be upregulated in most cancers and its inhibition is lethal to cancer cells. By regulating transcription of many tumor-related genes, protein translation, and alternative splicing it is indirectly involved in tumor growth and progression. It displays high selectivity for c-Jun, ER /β, and progestin receptor (PR), but does not affect other transcription factors, such as p53, c-fos, NF- B component p50 etc. This ZooMAbZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Reconstitution

300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
