Acidic Hair Keratin K33 (hHa3) polyclonal, anti-human, mouse

Quantity: 25 µl

Background:
The protein encoded by this gene is a member of the keratin gene family. As a type I hair keratin, it is an acidic protein which heterodimerizes with type II keratins to form hair and nails. The type I hair keratins are clustered in a region of chromosome 17q12-q21 and have the same direction of transcription.

Synonyms:
KRT33, HA3, HKA3, hHa3, KRTHA3

Isotype: Guinea pig Polyclonal (GP-hHa3)

Immunogen:
Synthetic peptide of human hair (trichocytic) keratin K33 (formerly also designated keratin hHa3; EKP IGS CVT NPC GPR SR), coupled to KLH

Form: Stabilized Serum

Specificity:
The antiserum stains specifically human hair keratin K33 expressed starting from the middle hair cortex. Because of high sequence homology both keratin isoforms K33a (formerly also designated keratin hHa3-I) and K33b (formerly designated keratin hHa3-II) are detected.

Reactivity: human, mouse

Applications: Immunohistochemistry on frozen sections, Immunoblotting

Working DIlution: 1:200 for immunohistochemistry; 1:2,000 for immunoblotting (ECL method)

Storage: 2-8C
