Every item is shipped based on the best shipping method assessed for the temperature requirements of that specific item. Items are grouped and shipped together whenever
possible, and a separate shipping charge will be included for each shipping method required. Shipping charges listed below are from our US warehouses to the Contiguous US,
Alaska, Hawaii, Canada and Puerto Rico. Shipping charges for countries outside the US and Canada will be determined once order has been received
Please note: We can not ship to PO boxes

SHIPPING METHODS & CHARGES
Ships via FedEx Ground to Contiguous US, Alaska, Canada, Monday through Friday. This method is used for less temperature sensitive items such as lab ware and animal
health products, bulky and/or heavy items
Labware ships FedEx Ground free of charge to the contiguous US
Heterogeneous nuclear ribonucleoproteins (hnRNPs) constitute a set of polypeptides that contribute to pre-mRNA processing and transport, and also bind heterogeneous nuclear RNA (hnRNA), which are the transcripts produced by RNA polymerase II. hnRNP complexes are the major constituents of the spliceosome and in particular, the hnRNP A1 protein is one of the major pre-mRNA/mRNA binding proteins and also one of the most abundant proteins in the nucleus. hnRNP A1 and A2/B1 regulate the processing of pre-mRNA by directly antagonizing the association of various splicing factors and by influencing the splice site selection on pre-mRNA. The majority of hnRNP proteins components are localized to the nucleus; however some shuttle between the nucleus and the cytoplasm. Most hnRNP proteins, including hnRNP C1 and C2, contain one or more RNA binding domains and are implicated in the processing of pre-mRNA. hnRNPs F and H are largely related factors that preferentially associate with poly(rG) regions on RNA. Isoforms of these proteins are often generated by alternative processing of the pre-mRNA and by posttranslational modifications such as phosphorylation on serines and threonines and methylation of arginines.
