Can anyone please help me to find the sizes (Da) for these human pituitary proteins? i have looked for them in Entrez and other bioinformatic sites, but am really not sure if they are right. Please, recheck them for me. Thanks a bunch! 1. Glycoprotein hormones alpha chain i have a vERY hard time with this one. from the Entrez result i only get Glycoprotein hormones alpha chain precursor form (13041 Da). i need an active form. What is the size? :yuck: 2. Variant hepatic nuclear factor 1 From entrez i got an active form of 166aa. Is this correct? 3. Human B-actin active form: 41737 Da. Correct? 4. Folate receptor alpha active form: 96 aa. Correct? Thanks !!!
